New Features
For full details, see What's New in Modo 11.1.
Alembic I/O Improvements
Alembic Streaming Improvements
Modo can now stream in geometry using Alembic Streaming Deformers and Alembic Streaming Meshes.
The Alembic Load Options dialog now has a Polymesh streaming options menu, which allows you to import geometry items and deformers into the current scene, enabling you to layout and render very large animated Alembic files exported from Modo and other Digital Content Creation software packages. In addition, particles, simulated meshes, curves, multiple UV sets, components of a mesh, and materials are also imported into Modo.
Alembic Export Improvements
There have been multiple improvements made to the Alembic exporting functionality, which complements the Alembic streaming improvements, to enable better workflows. Performance when exporting scenes with many key frames, deep item hierarchies, and replicators has been significantly improved.
The Alembic I/O option Include Unique Suffix In Item Names has been added to improve how item names are handled by skipping unique suffixes enabling you to preserve your naming conventions through the cycles of importing, modifying, and exporting Alembic files. The Force Letters and Digits Only Item Names option has been added to assist you in filtering exported item names to digits and characters, allowing better compatibility with Katana and Nuke.
Advanced 3D Viewport Enhancements
Advanced 3D Viewport
Performance improvements have been made to the Advanced viewport to speed up the frame rate.
The Display OpenGL Preferences now includes an AVP Allow Material Texture storage option. When enabled, it controls how the 3D Viewport stores its data internally in the textures or uniform buffers.
In addition, the following 3D Viewport properties have been added to improve performance:
• Shadows CSM - Sets the number of shadow buffer projections the Cascade Shadow Map system is allowed to use for the light source, allowing you to view casting curved shadows on curved surfaces.
• Shadows Size - Sets the texture resolution used when depth projecting the shadows. The following options are available: Low, Mid, and High. By default, this option is set to High.
• Shadows Filter - Sets whether the shadows are filtered. By default, this option is On.
• Material - Overrides the Shader Tree materials being used in the scene. This setting provides faster rendering performance results in the Advanced Viewport when rendering a number of different types of materials. These options are also useful when working with a Unity Material or Unreal Material.
Auto-Save
Auto-Save Cancel Option
Auto-Save is now preceded by a 10 second countdown with an option to cancel. The Cancel button and countdown appear in a small box on your current 3D Viewport. Pressing Cancel skips the current Auto-Save and launches at the next regularly scheduled Auto-Save interval.
Auto-Save Incremental
You can now set a number of incremental Auto-Saves in the Preferences > Auto-Save options. Consecutive auto-saves are now numbered and do not overwrite previous auto-save files. These file versions are prefixed with the version number and new auto-saves shuffle all the older numbered files down. For example, the most recent auto-save of MyFile.lxo is renamed 1_MyFile.lxo, the second most recent, 2_MyFile.lxo, and so on.
In addition, Auto-Save saves the current Preview rendered state, allowing you to pick up a progressive render from its last saved point when you open an auto-saved scene, rather than having to start the render again.
Direct Modeling
Topology Pen Improvements
The Topology Pen tool has a number of new options to improve the re-topology workflow. We have added a new Mode called Smoothing, several new Falloff options, new Smoothing options, and the following Miscellaneous options: Copy Discontinuous UVs and Keep Vertices.
Smooth Tool Improvements
The Smooth tool has new options to improve smoothing positions along boundary edges and corner vertices. Lock Boundary, Lock Corner, Lock Sharp Edges, and Sharp Angle options have been added. It is now available as a Procedural Mesh Operation.
Sculpt Smoothing Improvements
The Smooth mode of mesh sculpting is improved to maintain border edges and corner vertices of border polygons. The Lock Corner option locks the vertex positions at corner vertex where the valence is two or more.
Loop Slice Improvements
The Loop Slice tool now has a new option Select New Polygons. When enabled, this provides better visibility to see the selected polygons. A guide color is displayed for the slicing edges of the selected polygons.
Falloff Weight Tool
A new Falloff Weight Tool has been added, which creates a weight map and has similar functionality as the Soft Selection Falloff tool. Using the weight map generated by the Falloff Weight Tool is very useful for modeling, texturing, dynamics, rigging, and more.
Convert Falloff Cache
We have added a new Convert Falloff Cache tool, which allows you to convert internal falloff weights generated in Element Falloff and Soft Selection Falloff into a regular weight map. The internal cache stores falloff weight values for the last operation with Element Falloff or Soft Selection Falloff. This tool is enabled only when one of these tools is used on the active meshes.
File I/O
Setting, Loading, and Saving Scene Thumbnails
The Scene Item properties have two new options, Set Thumbnail and Load Thumbnail, enabling you to take a snapshot of your current scene from the 3D Viewport, Preview Viewport, and the Render Display and embed a thumbnail image into the LXO file.
Create Scene Templates and Load from the Preset Browser
You can now create a template scene by renaming any *.lxo scene file using the extension *.lxt and load these scenes from the Preset Browser.
General Workflow Improvements
User Channels
The Modo now allows you drag and drop channels onto mesh items in your scene to turn them into User channels.
GL Viewport Workflow Improvements
Disable GL Textures and GL Color Overrides
The Shader Item now includes aGL Display option to toggle on and off the display of textures in the Camera View to improve readability and performance when working on complex scenes. In addition, the Material item now has a new GL Override option. When enabled, Modo uses the defined GL Color values to change the color of specified polygons displayed in the Camera View without affecting the rendering in the Preview Viewport. This is useful when working on complex models containing a number of parts, which you want to apply different colors to.
3D Viewport Matcaps, UV Textures, and Environments
The 3D Viewport now has a Viewport Textures menu, allowing you to quickly select Environments, Matcaps, and UV Textures to display in the 3D Viewport. The UV Textures are used for UV Diagnostics. These changes do not affect the scene; they only change the viewport itself. This allows you to quickly view your scene with a Viewport Texture without having to add them to the Shader Tree.
Procedural Modeling
New Mesh Op - UV Create Operator
The UV Create tool works by projecting the polygons from a 3D space into the 2D (UV) space. The basic operation is the same as the standard UV Create Toolbox tool. In this release, you have the ability to create UVs using the procedural modeling process.
Square Option for Radial Sweep
The Radial Sweep tool now has a new Helix Generator Square option allowing you to align segments along a square. The Radial Sweep tool is also available as a procedural mesh operation.
Smooth Mesh Operator Improvements
A new procedural Smooth operator has been added to improve smoothing positions along boundary edges and corner vertices.
Rendering
Maximum Progressive Render Time
A new Max Render Time option has been added to the Progressive Rendering options to limit the rendering time when saving a frame to a disk. This option is used by the Preview Viewport with the default option settings enabled and with the Render Animation option enabled.
Scripting the Preview Viewport
The Preview Viewport can now be scripted (run) from a command line using Modo CL. There are now a number of new commands available to render a preview to an image, image sequence, and movie.
Preview Convergence based on Primary Render Output
A new Convergence option has been added to the Preview Viewport. When enabled, Preview checks that the image has converged to the minimum requirement (meaning the quality is good enough) before rendering the next frame. Setting this value produces faster results.
Preview Full Resolution Zoom
Zoom functionality in the Preview Viewport has been improved. You can now zoom in for a closer look without affecting the camera's position with a middle scroll wheel mouse. The view now snaps to 25%, 50%, 200%, 400% while scrolling your mouse button.
Unreal Bridge Plug-in
Server and Client Plug-in
Modo now has the ability to communicate with the Unreal Engine in real-time. To improve the workflow for Game Engine users, you can use a network protocol to share data between Modo and Unreal using the new Modo Bridge plug-in. The connection between Modo and Unreal can be on the same machine, across multiple machines on the LAN, or even possibly remotely. An entire scene or selected elements from a scene can be pushed bi-directionally and updated between the Client and Server. Mesh geometry, normals, UVs, textures, materials, as well as scene hierarchy, lights, and cameras can be synchronized between both applications.
UV Tools
UV Coverage Indicator
A new UV Coverage value is displayed at the bottom right corner of the UV Editor, which shows the amount of uniform UV space of the total region that is covered by geometry. This option is useful to game workflows, when trying to maximize the amount of texture space being used for the target surface. When you use a UV editing tools, the coverage is updated at the end of the editing process.
UV Box Transform
A new UV Box Transform tool has been added, which allows you to quickly move around groups of polygons in UV space. This tool, while active, draws a rectangular bounding box around the component selection in UV space, to which you can apply transform actions.
Distortion Compensation
A new Distortion Compensation option has been added to reduce the distortion automatically to produce cleaner UV maps. This is useful when working with primitives that do not have equal radius values. The aspect ratio and related area size of UV polygons conforms to the 3D polygons. This option as been added to the following primitives: Cube, Cylinder, Capsule, Sphere, Torus, and Ellipsoid.
Split Command
A new Split tool has been added allowing you to split UVs along the selected geometry (along selected edges, around polygon selection boundaries, or on vertices). It doesn't offset the UVs, but once split, you can move the polygons independently.
Split and Sew
The Split and Sew tool is now more interactive. The tool now acts as a brush, with a radius. "Painting" over vertices in UV space can split them apart, with the brush radius controlling how far they are offset from their starting position. Holding a modifier key sews the edges together instead of splitting them.
UV Tear Off Qualifier Key
Qualifier keys have been added to enable the Tear Off option to separate and move your selection of polygons to a new position on your UV map. Holding down the Ctrl/Cmd + Shift keys, while dragging, temporarily enables Tear Off mode.
UVs to SVG Real World Scale and Units
The Export UVs to SVG feature has been enhanced to give you better control over the real-world size of your SVG output. This can be helpful both for creating templates to create UV-based textures in external applications, and for applications like packaging or shoe creation, where a pattern with accurate real-world dimensions must be created from a mesh's UVs.
UV Relax Improvements
The Boundary option has been added to the UV Relax tool, which includes a number of options used to relax boundary UV vertex positions, replacing the Lock Boundary and Straighten options used in our previous release.
UV Overlapping Selection
A new Select Overlapping Polygons tool has been added to assist you in detecting errors with UV mapped polygons. This tool provides three options to assist you in locating these errors - Cross Intersection, Self Intersection, and Flipped.
Texel Density
A new Texel Density tool has been added to improve the Games workflow. This tool enables you to quickly scale the size of UV islands or individual polygons such that they span roughly the same number of texture pixels per meter of real size. This is useful when you are dealing with texture density mismatches, in some cases you may either have differently sized UVs or textures, resulting in visibly over-detailed or under-detailed areas relative to the rest of the asset or scene. Making the texel density more uniform can help maintain a standardized level of texture detail across an asset or environment.
New Default UV viewport Settings
The default viewport display settings to view UDIM Tiles on an UV map have been updated. The UV viewport now shows a 0 to 1 space by default, instead of -1 to 1. The UDIM tile number display is enabled by default, but it is only shown if more than the 0 to 1 space is shown.
Vertex Normal & Baking Improvements
Use Polygon Area Smoothing Option
A new Use Polygon Area option has been added to the Material item, which enables you to smooth vertex normals to correct shading problems. Modo calculates the weight contribution of vertex normals and averages that value by the polygon area. Use this option to improve smoothing and shading for a mesh that has large polygon faces connected to small polygon faces. For example, when there is a fine beveled face beside a big face.
Vertex Illumination Baking Type and Output Options
The Vertex Illumination Baking tool has been renamed Vertex Shader Baking. In this release, new Bake Type and Output Channel options have been added to this tool. Use these options to control what Modo bakes and where it stores the result of the bake.
Object Space Normal Maps
To improve the Games workflow, we have added Object Normal maps to encode the texture direction in absolute terms in object space. This is typically used in games workflows for static, non-deforming objects (environment, props, and so on) to quickly render in the game engines.
Baking Aids
Items now have a contextual menu for baking certain mesh features. A number of baking tools are available in the Mesh Operations list from the Bake contextual menu. From this menu, you can bake occlusion, illumination, normals, displacements, texture effects, vertex shadings, vertex curvatures, and bake to an Alembic file. The bake commands start a process of generating UVs, packing them, doing a bake (through a bake item) and then save the resulting bake to an image that can be added to the Shader Tree automatically.

Known Issues and Workarounds Specific to Modo 11.1
This section covers known issues and gives workarounds for them, where appropriate.
Advanced Viewport
• ID 50810 - Anisotropic texture filtering is lower quality than in the Default viewport.
• ID 46995 - Ambient Occlusion display in the Advanced viewport is affected by selected item wireframes.
You can disable Show Selection in the Visibility options or disable wireframe drawing on the active mesh layers.
Animation
• ID 53661 - Selecting actions does not always select the correct one. This is caused by copying actions.
As a workaround, manually edit the tags on the broken actions by selecting them in the Groups tab, then save and reload the scene.
Assemblies
• ID 36452 - Assemblies exported from the Item List context menu result in poor visual layout of nodes on import.
As a workaround, you can save assemblies from the Schematic viewport.
Baking
• ID 50671 - Baking displacement maps can cause UV seams to be visible, and the baked displacement map to show quilting effects and other render artifacts.
• ID 49437 - The Bake Channel Swizzling option can’t bake to texture alpha.
Color Management
• ID 49244 - (Windows only): With Perform Color Correction on, setting a default scene to a scene with a mesh that has a position channel crashes Modo at launch.
As a workaround, use System > Reset Preferences to reset to defaults or move/remove the default scene.
Default Viewport
• RGBA textures only draw correctly in the Advanced viewport. In the Default viewport, any unsupported texture effect on an image map is drawn as diffuse color when the layer is selected in the Shader Tree.
Deformers
• ID 55470 - Freezing a mesh with normalized deformers and a Mesh Op caused Modo to crash.
File and Image I/O
• ID 55439 - Alembic imported convex polygons with at least two close to co-linear edges may not draw correctly in GL (appearing as missing triangles).
As a workaround: Import using the new Alembic Streaming options. Set the Polymesh streaming options to Alembic Streaming Meshes (polys only, force all). Alternatively, select the base material in the Shader Tree and enable Surface Normal > Double-sided, then change the Smoothing angle to 180.
• ID 50198 - Alembic scenes don't export some surface items, including static meshes and procedural shatter items.
• ID 49728 - Exporting selected layers (from the Item List context menu) to .fbx doesn't export instances, unless the original mesh is also exported.
To resolve this, set the .fbx preference to Export Selection and use Export As….
• ID 47036 - Color management in .svg images is not currently supported. This is a side-effect of a bug fix where the largest allowable image size (64k x 64k) was always used when color correction was enabled.
• ID 46962 - Rendering .svg images used as stencil maps for displacement or for layer masking can be very slow.
Fur
• ID 35731 - Fur length textures can’t be edited with the Stretch tool.
Use different fur length drivers, such as hair guides or vector vertex maps.
General
• ID 49514 - Mac OS X only: Running modo_cl before running the UI Modo application breaks code signing.
As a workaround, start the UI version of Modo once, before running modo_cl on any system where you later intend to use the UI version.
GL
• ID 55816 - Wireframes are washed out on transparent surfaces in the Advanced viewport.
As a workaround, avoid transparency when modeling or doing work where wireframes are needed. Alternatively, use the Default viewport.
• ID 55746 - Moving the mouse over a procedural mesh, when Animation > Enable Deformers is off, may cause Modo to crash.
• ID 55594 - Wireframe overlay is missing in orthographic views if Line Antialiasing is set to Full in the Advanced viewport.
As a workaround, use the Line Antialiasing > System or Off option instead.
• ID 55500 - Setting the Advanced viewport Effects > Material option to Basic displays Unreal materials as white.
As a workaround, use Simple mode.
• ID 55145 - Default viewport lights are not casting shadows in the Advanced Viewport.
• ID 54456 - GL count is incorrect in certain circumstances, including when meshes are displayed in wireframe mode or when displaying replicas.
• Windows only: Using Raptr can cause GL driver crashes in Modo.
Input Devices
• ID 51741 - Mac OS X only: Modo sometimes becomes unresponsive when using the combination of a click-drag in a tree view (for example, when toggling the visibility of two successive items in the Shader Tree), followed immediately by a two-finger scroll gesture on some devices, including laptop trackpads and the Magic Mouse.
As a workaround, change to a 3-button mouse (recommended to fully access all of Modo's features).
• ID 35856 - Linux only: Plugging in a Wacom tablet while Modo is running can cause undesired movement. This cannot be fixed, due to a limitation of the hardware driver.
To avoid this, plug in the tablet before application startup or restart.
Item List
• ID 53209 - Group creation (Ctrl + G) places the new group folder at a random position in the Item List, if the items are not selected in a top down sequence.
As a workaround, select the items being grouped from top to bottom in the Item List before grouping (Ctrl + G).
Modeling
• ID Bug 55857 - Using the Model layout Toolbox Basic subtab Center Selected option on a polygon selection, with multiple mesh layers selected, doesn’t center to the origin.
As a workaround, select only one mesh layer at a time or put all geometry in one layer.
• ID 55842 - Using the Tack tool, with Align, Copy Geometry, and Make Bridge options enabled may cause Modo to crash.
• ID 32728 - Zooming out with a Space Navigator alters the Work Plane position.
Network Rendering
• ID 30318 - Network Rendering doesn’t support Realflow particles.
• ID 25636 - Frame passes are not supported.
• Several Bugs - While it apparently worked in Modo 902, in some cases, Network Rendering was not implemented to support baking. Changes to Modo in the 10-series apparently broke what was working for some artists, so the functionality has been disabled.
As a workaround, Modo 10 implemented the ability to Network Bake using Bake Items and an external render controller. For more information, please see the SDK Wiki.
Node Shading
• ID 50642 - Nodal shading does not support UDIMs.
Painting/Sculpting
• ID 41682 - Textures are not always updating in Preview/Render when painting on an image map.
You can save and reload the image to force the update.
Particles
• ID 44551 - Surface Particle Generators may not update with changes to a Density Gradient Input set to Slope.
As a workaround, choose Distance to Locator or any other setting from the Density Gradient Input dropdown, then change it back to Slope.
• ID 34925 - Re-opening scenes saved with large particle caches can cause problems.
To avoid such issues, delete the cache before closing Modo, or export the particles to .csv cache files or Realflow .bin files. You can do this by attaching one of those nodes to the Particle Simulation item in the Schematic viewport, and clicking Cache Simulation.
Preset Browser
• ID 55882 - Pinning the Viewport Textures preset browser crashes Modo on restart.
As a workaround, run Modo in Safe Mode and select System > Reset Preferences or manually delete the main config file.
Presets
• ID Bug 55867 - Dragging and dropping a preset material into a material group places the preset above the Base Material, not in the group.
As a workaround, move the preset material group after dragging and dropping it.
Preview
• ID 55901 - Preview is rendering images with the wrong color space for non EXR images.
• ID 55646 - The Camera can’t be edited in Preview if any of its channels are locked.
• If a high poly mesh is not visible, the Preview baking output will be incorrect.
As a workaround, reset Preview to fix the baking.
Procedurals
• ID 52149 - Curve Extrude mesh operation: The Path Segment Generator's Align to Normal option doesn't work when using a Bezier with zero-length tangents.
As a workaround, rotate the polygons to point toward the +Z before extruding or make sure there are no zero-length tangents.
• ID 49767 - Scenes, which contain a UV constraint modifier driving texture properties, may fail to load after saving, due to a modifier dependency loop.
• ID 46512 - When rigged, Rock items and other procedurals do not display correctly in GL. This is a limitation of the feature and will not be fixed.
You can use Preview or RayGL to visualize the variations from rigging.
Projections
• ID 49473 - Projections are incorrect if the projecting camera is set to Vertical film fit mode and the width is less than the height.
• ID 43771 - Camera projections from non-render cameras show distortion in GL and baking.
To avoid this, make sure that the projection camera has a film width-to-height ratio that matches the main render camera.
References
• ID 44492 - If a scene that already contains references is referenced, the shading of the original references may not persist.
As a workaround, limit scenes with shading to one level of reference.
• ID 41119 - Reloading a reference after replacing it with the same file can cause Modo to crash.
Rendering
• ID Bug 55787 - The Scratches procedural texture may produce NaNs in the Preview viewport and Render Display.
• ID Bug 55663 - Motion Blur applied on a curve in a Mesh Operation no longer works.
• ID Bug 55262 - Displacement combined with normal maps renders incorrectly.
As a workaround, enable the Displacement as Bump option in the Render Item Settings or render using Preview.
• ID 53411 - Mesh lights or any direct light too close to a surface can produce fireflies (hot pixels) in some cases.
As a workaround, use a Maximum Radiance higher than 1 W/srm2 to reduce the bias.
• ID 53184 - Value presets created for material Subsurface Scattering samples in Modo 10.1 or earlier now show on the render item instead.
• ID 52730 - The Vertex Illumination Bake command doesn't work as expected, when the mesh has transform channels.
As a workaround, freeze the transforms in the mesh properties.
• ID 52011 - Tangent Basis handles Mirror UVs incorrectly.
As a workaround, apply Mikk or any other tangent space basis to the mesh before baking.
Rigging
• ID 55059 - Binding can’t be used multiple times in Setup mode.
As a workaround, exit and re-enter Setup mode.
• ID 27244 - Duplicating joints in a bound mesh retains influences from the original joint chain.
Schematic
• ID 55859 - Dragging and dropping a Texture Locator, Camera, or Light from the Shader Tree into Schematic viewport doesn’t work.
As a workaround, with the item selected, click the Add Selected button in the Schematic viewport.
Scripting
• ID 53458 - Right-clicking or running a script in the Script Editor can lock up input to Modo.
As a workaround, click in the top window of the Script Editor, use the main menus, or change to another application, then switch back to Modo.
• ID 55138 - Modo crashes when undoing a script which uses removeItems.
Sculpt
• ID 55897 - Specular and shadows in the Default viewport stops showing when sculpting on a displacement image.
As a workaround, use another viewport mode such as Advanced or Reflection, or apply a Matcap shader to the Shader Tree.
Shader Tree
• ID 37858 - In the Shader Tree, choosing a group from Add Layer > Image Map > (use clip browser) fails.
To work around this issue, in the Clip Browser, choose a single image instead of the group, and then change to the image group using the Texture Layer's Properties tab.
• ID 30947 - Layer masking displacement does not work unless you drag and drop the masking layer onto the displacement layer.
Topology
• ID 55887 - In Remove mode, the Topology Pen doesn’t remove edges created by the Split mode but instead removes the underlying polygon.
Unreal and Unity Materials
• ID 50701 - Unreal material Ambient Occlusion does not bake correctly in Modo.
• ID 50700 - There is no way to visualize the Unreal SubSurface Color effect in Modo.
• ID 50451 - On some graphics cards, Unity material may cause flickering in the Advanced viewport when used with bump maps and shadows.
UI
• ID 55759 - Transforming objects can cause the Items Properties panel to flicker.
• ID 55702 - Mac OS X only: Saving layouts on certain multi-display configurations caused Modo to crash.
As a workaround, having your primary display as the left-most, may prevent this.
• ID 55571 - Resizing the dopesheet in Zen crashes Modo 11.1, but not in Modo 11.0.
• ID 44496 - Mac OS X only: Disabling Affect System Color Dialog in Preferences > Rendering > Color Management, and using the system color picker causes colors to darken with each use of the color picker.
This is due to an OS X issue, which requires the color profile in both the monitor settings and color picker to be set to sRGB IEC61966-2.1.
• ID 44896 - Dragging and dropping an image from disk into the Clips list doesn’t work.
If the Clips list is empty, drop the image onto the bar at the top, otherwise drop it above or below other images in the list.
• ID 43162 (Windows only) -Setting a custom text size affects Modo's text drawing.
As a workaround, go to the compatibility settings by right-clicking the Modo shortcut or executable, and turn off font-scaling for the application.
UV
• ID 55891 - Show UDIM does not display the UDIM number in the UV viewport.
As a workaround, enable the Auto Spans option.
• ID 55582 - The Tear-off modifier keys (Shift+ Ctrl) are live in the UV Transform tool, meaning the Tear-off state changes during the drag if the keys aren’t held down.
• ID 55564 - The UV Distortion and UV Vertex maps are no longer accessible. This is due to bugs and crashes with these ‘internal’ maps being visible to users. Modo 11.2 will introduce features to replace prior uses of these maps.
Developer Notes
• ID 55171 - Scripting: The polygon.getIsland() function enters an infinite loop in some circumstances, which caused Modo to stop responding.
• ID 54157 SDK: Documentation - Added a description for CLxValue StreamIO (class).
• ID 54716 SDK: TDSDK (Mac OS only) - Fixed issue where Point IDs sometimes returned as Ints rather than Longs.
• ID 54863 SDK: Render Cache no longer crashes while working with multiple scenes.
• ID 54998 SDK: Render Cache - Fur and Curve export are now working as expected.
• ID 55103 SDK: Modo no longer crashes when batch processing many scenes.
• ID 55176 SDK: Documentation - Command as Filter is now documented. For more information, see Form Filtering.
• ID 55194 SDK: TD SDK - Selection is now working as expected.
• ID 55615 SDK: PlatformService.AppVersion() is now returning full version numbers (For example, 1111, for 11.1v1).
