Minimum System Requirements 

 

Hardware Requirements 

Ornatrix heavily relies on your system's CPU, GPU, and RAM to model, simulate, and render millions of high-fidelity hair strands. For optimal performance, we recommend using a modern CPU (Intel or AMD) with a high core count and high clock frequencies, paired with at least 16 GB of RAM.

 

Windows 

• Windows 10 or newer
• Maya 2018 or newer.
• VC 2019 runtime

 

Mac 

• OS X 10.15 Catalina or newer
• Maya 2018 or newer.

 

Linux 

• CentOS 6 or 7, corresponding to Maya's requirements.
• Maya 2018 or newer.
• Starting with Ornatrix 4.1.4, a Linux distribution from the Red Hat Enterprise Linux 8 family is required. Support for the Red Hat Enterprise Linux 7 family has been discontinued.

 

Known Issues and Limitations 

• Dynamics Node
  The Dynamics operator has been deprecated and is not supported on macOS. Please use the Moov Hair Physics node as an alternative.

• Maya 2020
  Maya 2020 Update 1 is required, as the initial 2020 release contains a bug that affects Ornatrix.

• Maya 2025
  Starting on Maya 2025, the Expression Editor widget is no longer included. The plain text Expression Editor is still available for adding and editing SeExpr scripts.

 

Viewport Hair Display Limitations on Mac OS 

The version of OpenGL included with macOS lacks support for compute shaders and other essential features required by Ornatrix for optimal viewport hair display. Due to this limitation, the following Ornatrix features are not available when using macOS:

• GPU Hair Display
  The ability to leverage GPU for hair display in the viewport.

• Camera-facing Hair
  Hair strands dynamically aligning with the camera view.

• Camera-facing Normals
  Strand normals dynamically aligning with the camera view.

• Display Strand Selection
  Displaying strand selection directly on the Hair Shape node. This does not apply to Edit Guides.

• Display Strand Groups
  Displaying of strand groups colors directly on the Hair Shape node when Edit Guides is not selected.

• Overlay Opacity and Overlay Blend Mode
  Since none of the Overlay features are supported, these options will not have any effect.

• Display Wireframe when selected
  Allows you to disable the selection highlight of the hair in the viewport.

• Display Strand Channel Overlay
  Allows you to display the values of the selected strand channel.

• Maya LT
  Maya LT does not support third party plugins. You can find more information in Maya LT Documentation*
