Exception has occured...
I'm getting an exception thrown when I try to run a test scene following this example. Here is what it's saying to me:
Error #9 Function: CgProgram::loadFromSource Description: Unable to compile Cg program BasicTexture_PS: CG ERROR: The compile returned an error. (20):error C1008: undefined variable "diffuse" (20):error C1115: unable to find compatible overloaded function "tex2d"
I know it's because "diffuse" wasn't defined, I just don't know how to do it. I can see in the example code it's referenced, but not defined. Please fix this!
