Troubleshooting - WARNING : 3000 - RT shader DLL (Cg Shaders.dll) not found in path

Problem

When you try to use one of the Cg realtime shader nodes, or do an OGL preview of Ultimapper, you get this warning:

WARNING : 3000 - RT shader DLL (Cg Shaders.dll) not found in path

Solution

This warning almost always has nothing to do with Cg_Shader.dll. Rather, it usually means that XSI cannot find the Cg Toolkit (http://developer.nvidia.com/object/cg_toolkit.html).

Reasons why you may get this warning:

• You don't have Cg Toolkit installed. Older versions of the Cg Toolkit (eg 1.4) will also cause this warning.

• The PATH environment variable does not include the Cg Toolkit bin folder (usually C:\Program Files\NVIDIA Corporation\Cg\bin).

• The PATH environment variable also includes the location of an older version of the Cg Toolkit (eg a version of the toolkit used by some other software).

So, the solution is to install the Cg Toolkit 1.5 Beta, and check the value of your PATH environment variable.
