New Project Dialog

The New Project dialog is described below with functions for how to access it. A list of the controls on the dialog box can be found in the table below.

What It Does

The New Project dialog lets you select geometry and various options for a new Mari project. Use the Path control to select an .obj, .ptx, .abc, or .fbx file you want to use in the project.

Resize the dialog box to display long filenames or select multiple files to display more than one geometry, if they are of the same file type. Mari checks the model for any errors that might prevent it from processing, for example, whether UVs overlap or touch border edges. A Mesh Sanity Check dialog displays any warnings or errors. (Errors cancel opening the model, but you can continue with warnings.)

Depending on the size and complexity of textures, it can take several minutes the first time you load them into a Mari project. Once saved, however, the project should open quickly in future.

New Project Dialog Box Fields

Control	Type	What it does	Opens this dialog box	Notes
Project Name	entry box	Lets you specify the name of the project.		This is for you to identify the project only (this is not a filename).
Geometry
Path	entry box, dropdown, button	Opens .obj, .ptx, .abc, or .fbx files. Dropdown lists the last 10 opened. Once you select a file, the Mesh options appear under the root Path.	Pick Mesh dialog	Select by either typing the Path, selecting from the dropdown of the last 10 files selected, or clicking the button to browse to a file.
Mesh options \| Mapping Scheme	dropdown	If there is a UV map available, and you would like to use it, select UV if available, Ptex otherwise. If you prefer to use Ptex, select Force Ptex. This option loads the selected geometry and replaces the existing UV map with a Ptex map.		Only available when choosing .obj, .abc, or .fbx files in the Path.
Mesh options \| Selection Groups	dropdown	Selection groups have two options, to either: • Create From Face Groups - this is the default behavior and allows the use of selection groups in Mari. • Don’t Create - if you choose not to create a selection group, Mari does not create any from the file.		Only available when choosing .obj files in the Path.
Mesh options \| Multiple Geometries Per Object	dropdown	If your .obj consists of multiple geometries, you have the option to Merge Geometries Into One, which is the default behavior, or Create Separate Geometries (Ptex Only). If you select Merge Geometries Into One, Mari combines the individual geometries into a single geometry, while selecting Create Separate Geometries (Ptex Only) creates individual geometries.		Only available when choosing .obj files in the Path. Even if you select Create Separate Geometries (Ptex Only), Mari only displays a single geometry on the canvas. However, when you export a channel you have the option to export individual .ptx files for each geometry.
Mesh options \| Start Frame and End Frame	entry box	Set the frame range from the source file to import.		Only available when you are loading an animated sequence using the .obj, .abc, or .fbx formats.
Mesh options \| Single Frame	button	Sets the other fields to only import the first frame from the animation in the object file.		Only available when you are loading an animated sequence using the .obj, .abc, or .fbx formats.
Mesh options \| All Frames	button	Sets the other fields to import the entire animation from the object file.		Only available when you are loading an animated sequence using the .obj, .abc, or .fbx formats.
Mesh options \| Merge Type	dropdown	For Ptex files, there are two choices for the geometry mesh options: • Separate Meshes - creates only one object with one geometry. • Single Mesh - creates only one object, but has multiple geometries within it.		Only available when choosing .ptx files in the Path. The option to Separate Geometry In One Object is essentially the inverse of the Ptex channel export process, and allows project reconstruction.
Mesh options \| Merge Type	dropdown	Choose whether to merge selected items from the objecthierarchy tree as: • Single Mesh - merges selected geometry into one single mesh in a GeoEntity. Note: Note that this implies that the information about the original geometries cannot be accessed once the merge is done. • Just Merge Nodes - merges selected geometry into one GeoEntity while retaining the metadata and mesh information about the original individual geometries. Note: This information can only be accessed by more technical artists using the C API. see, Software API Overview.		Only available when choosing .abc or .fbx files in the Path.
Mesh options \|Merge Selection Groups		You can choose to Merge selection groups with the same name or choose the Do not merge selection groups option.		For more information on selection groups, see Selection Groups.
Mesh options \|Take	dropdown, information	If an object has been exported as part of an .fbx file with animation takes, the takes are shown in the dropdown menu. Otherwise, information regarding the only take available is shown.		Only available when choosing .fbx files in the file browser. When adding an object with animation takes, the take can only be selected on import and cannot be changed at a later point.
Mesh options \| Scene	information	In the object hierarchy, shows all the geometries or meshes, cameras, and groups that are part of the selected Alembic file. Expanding the parent row, reveals the child geometries beneath it.		Only available when choosing .abc or .fbx files in the Path.
Mesh options \| Merge	checkbox	Select the checkbox to determine if a geometry is to be merged with another on project creation.		Only available when choosing .abc or .fbx files in the Path. For more information on merging Alembic or FBX geometry, see Creating a New Project with Alembic and FBX Files
Mesh options \| Frame Offset	entry box	Set by how many frames to offset the loading of an animated object. You can specify a frame range, or simply a number of frames.		Only available when choosing .abc files in the Path.
Channels
Root Path	dropdown, button	Displays the root path for the project. This is where Mari looks for any existing textures to import as it creates the channels.	Choose Base Path dialog	This is the value that Mari substitutes for $PATH in the import templates in the bottom list.
Scan	button	Scans the Root Path for any existing texture files.		After scanning the Root Path, you should always set the Size of the texture files manually. The default values Mari sets may not be correct as channels can contain many different patch sizes.
Category	dropdown	Selects a Mari channel preset template from the list of available shaders.		AiStandard - VFX, BRDF - Games, BRDF - VFX, General, Principled BRDF - Metallic - Games, Principled BRDF - Metallic - VFX, Principled BRDF - Non Metallic - Games, Principled BRDF - Non Metallic - VFX, Unreal - Metallic - Games, Unreal - Metallic - VFX, Unreal - Non-Metallic - Games, Unreal - Non-Metallic - VFX, VRayMtl - VFX
Template	dropdown	Specifies a channel template to control the format of the filenames when Mari looks for existing textures on disk.		For more information about channel templates, see Defining Custom Channel Templates, Reviewing the Custom Channel Template File Format, and Example File: DefaultTemplates.mtt.
Prefix	entry box	Specifies the filename prefix for existing texture files, if applicable.
Create	checkbox	When enabled, creates a shader and connects channels to the shader on project creation.		Most presets contain enabled channels by default.
Import	checkbox	Imports existing textures into the channel after creating it.
Name	information	Specifies the name of the channel to create. Mari sets a default value, but you can change this.		For example, color, specRough, dispFine, dispBroad, colorDetail, colorDetailMask.
Size	dropdown	Specifies the patch size for the new channel. Mari sets a default value, but you can change this.		256x256, 512x512, 1024x1024, 2048x2048, 4096x4096, 8192x8192, 16384x16384, 32768x32768
Colorspace	dropdown	The colorspace in which the colors within your project are interpreted. Either select from the shipped config files or allow Mari to set an Automatic colorspace.		You can change these settings within the project after project creation, if necessary.
File Space	dropdown	Specifies the file space used when generating vectors. Mari sets a default but you can change this.		Normal, Vector, Vector (flipped Y), or Normal (flipped Y)
Fill	swatch	Specifies the color to fill the new channel. Mari sets a default value, but you can change this.		Click the swatch to change the color.
Depth	dropdown	Specifies the color depth size. Mari sets a default value, but you can change this.		8bit (Byte), 16bit (Half), or 32bit (Float).
Files	entry	Specifies the filename template used to pick existing textures to import into the channel. Mari sets a default value, but you can change this, or you can use the button to open a dialog allowing you to manually pick the files.		This option is ignored if the Import checkbox is disabled.
	button	Opens a dialog box allowing you to pick the textures for Mari to import into the new channel.	Import Dialog
	image	Indicates that Mari has not found any textures to import.		If there are textures to import, Mari displays the number of patches available.
Color Settings Note: All of the following Colorspace options can also be changed after project creation, if you decide you no longer want to use the colorspace setting that was chosen during project creation.
Color Management Enabled	checkbox	Enables or disables the OpenColorIO color management.
OCIO Config	dropdown	A list of either user-defined config files (Custom) or shipped OpenColorIO config files that handle colorspace.
Custom OCIO Config	entry box, button	If you chose Custom for the OCIO Config file choice, specify the filepath to the config file.
Color Monitor	dropdown	The default colorspace, which applies to thumbnails and UI elements. Typically, this should be the same colorspace as you intend to use for the canvas.
Scalar Monitor	dropdown	The default colorspace for all user interface elements which are displaying non-color managed (i.e. scalar) swatches, pickers, and thumbnails. (To understand the difference between color and scalar data in Mari, see Color Data and Scalar Data). This preference does not affect the canvas and image viewers, however it is recommended to set this to match the scalar View Transform. (The active selection can be changed using the View Transform Toolbar .)
Color Picking (advanced and intermediate color management modes only)	dropdown	The colorspace for all color pickers, swatches, and image viewers.
Working (advanced color management mode only)	dropdown	Default for painting, lighting, applying filters, and similar operations. Typically, you'll want to select the same linear-based colorspace as your 16/32-bit float channels to get accurate results.	Working (advanced mode only)	dropdown
Blending (advanced color management mode only)	dropdown	Default for applying blending operations such as: a comp of the paint buffer and the current paint target, blending between layers, and combining inputs in a merge node. Typically, you'll want to set this to Same as 8 bit Data to get the same results as painting prior to Mari 3.0, and to get less banding artifacts when painting 8-bit channels and images.	Blending (advanced mode only)	dropdown
8 bit Color	dropdown	The default colorspace for 8-bit channels, and reading and writing image files with 8-bit data.
16-bit Integer Data	dropdown	The default colorspace for 16-bit channels, and reading and writing image files with 16-bit data.
8-bit Scalar	dropdown	The default colorspace for masks, heights, normals, depths and, generally, any non-color image with 8-bit data.
16/3-bit Float Data	dropdown	The default colorspace for 16- and 32-bit (float) channels, and reading and writing image files with 16- and 32-bit, floating point data.
Lighting
Shader	dropdown	Specifies the shading model from one of the following: • Current Shader • Current Channel • Current Layer & Below • Current layer • Current Paint Target
Lighting	dropdown	Specifies the lighting on the main mesh. Mari comes with five default modes for lighting the model, and optional shadow control: • Flat - a flat, uniform, directionless light. • Basic - basic diffuse lighting without specular. • Basic with Shadows - basic lighting with diffuse lighting, as well as shadows. • Full - full lighting with diffuse and specular lighting. • Full with Shadows - full lighting with diffuse and specular lighting, as well as shadows.
Active Light Count	entry box, slider	Specifies the number of active directional lights.
Environment Map	arrows, preview button, file browser, reset	Click the blank image space to choose an environment from the Mari Environment library. Clicking either of the arrow keys cycles backwards or forwards through the Mari Environment library, loading the image as it does. Clicking the file browser opens the Open an Image dialog. Select an image of any of the file formats listed in the File of Type field. You can also drag-and-drop an image from a file browser onto the blank image space to load the image as an environment light.		For more about the options in the dialog, refer to Open an Image Dialog.
Create New Project	button	Creates and opens the new project.
Cancel	button	Cancels the new project creation.
