Release Notes for Modo 17.0v2

Release Date

21st March 2024

OctaneRender Prime

Differences between the Prime and Studio+ versions of the plugin

  • The Prime version is packaged free with the Modo 17 installers for Windows, Linux, and macOS Apple Silicon (ARM). It is not available in the macOS Intel (OSX) builds.

  • Octane render requires an NVIDIA card to run on Windows or Linux, and Apple Silicon hardware on macOS

  • The Studio+ version is purchased separately from OTOY via a subscription - https://home.otoy.com/render/octane-render/purchase/

  • The Studio+ version has the following features that the Prime version does not:

    • Rendering on more than one GPU

    • Network Rendering

    • NVLink (connection between multiple graphics cards)

    • Octane LiveDb (material and textures library)

    • Integrated RNDR (cloud rendering). RNDR is still available for manual ORBX file uploads.

    • There is no Prime version of Octane Standalone, so if you want to render in Octane Standalone (for vertex motion blur - see below), you will need to purchase a Studio+ subscription. The Demo version of Octane Standalone can also be used for rendering scenes exported from the OctaneRender Prime plugin.

OctaneRender for Modo (Prime and Studio+) Limitations

  • Camera and Object (Mesh Transforms) are supported but Vertex motion blur is not - see https://render.otoy.com/forum/viewtopic.php?f=34&t=73940 for details and workarounds.

  • Modo Shader Tree support is limited. Octane uses a node-based system to define materials, which is very different from Modo's Shader Tree. In general, you will let the plugin convert the Modo Material to an Octane Material when the render starts, and if the conversion needs adjustment, add an Octane Override to the Material Mask and make the adjustments with the Octane nodes in the Modo Schematic.

  • Some Modo functions require additional scripts for support. For example, rendering out Render Passes. These scripts are available from https://render.otoy.com/forum/viewtopic.php?f=34&t=78755

Manual and Tutorials

FAQ

  • How can I get up-to-date imformation on the plugin

  • How often are the Prime and Studio+ versions of the plugin updated

    • The Prime version will be updated with at least each point release of Modo and sometimes during v-updates.

    • The Studio+ version is updated more frequently, and is generally available for the latest Octane release

  • Can I have the Prime and Studio+ versions installed at the same time

    • Yes, however only 1 kit can be enabled. The other needs to be disabled via the Modo Preferences menu

    • Starting with Modo 17.0v2, there is now an environment variable which can be set to disable loading the internal OctaneRender Prime plugin. Set NEXUS_KITDISABLE=OctaneRender_Prime

    • Due to a bug in the Octane libraries, if both the external kit and internal kit are enabled on macOS Apple Silicon, Modo will crash on launch. In this case, first uninstall the external kit, then start Modo and disable the OctaneRender_Prime kit or use it. Or set up the environment variable described above.

  • How do I report bugs?

  • How to I submit Feature Requests

  • How do I fix an issue where one of the plugin forms is not showing correctly, or Modo is crashing on startup

    • Delete your MODO[version].CFG files and restart Modo.
