Limitations of CgFX shaders

Known limitations for the CgFX shader include:

• Only .cgfx files and not .cg are supported
• Pre and post effects (for example, full-screen effects, global effects, multi-pass effects)
• Pass scripting
• Cg Interfaces
• Time semantic: When using a shader that moves with time, you must refresh the scene in order to see the animation, for example, by tumbling the camera.

Important information about the CG language including the limitations of the CgFX plug-in are available on the nVidia website (www.developer.nvidia.com), especially https://developer.nvidia.com/cg-toolkit.

Shaders that deform geometry are not supported.

You must use an nVidia graphics card if your CgFX shader utilizes nVidia specific profiles. Otherwise, you will not be able to preview these shaders in the scene view.

Note:

On the Linux platform, the Maya hardware workspace does not support the GLSL or Cg shading languages on remote display or any indirect rendering device.
