Troubleshoot custom mental ray shaders

Advanced filtering and file textures

Scenes that contain custom shaders for volume effects or environment shader may not render correctly with advanced filtering (quadratic, quartic, etc.) for file textures.

Workaround

Use mipmap filtering, or turn off filtering.

Custom mental ray shaders and importing or referencing

Imported or referenced Maya 5.0 files containing mental ray shaders, with color, scalar, or texture parameters, do not correctly convert in the current release of Maya. You may notice shaders becoming disconnected.

Workaround

Open the Maya 5.0 scene file in Maya Interactive, and save it. Then import or reference the file in the current release of Maya.
