displacement mapping using Cg

Hi

Can anyone tell me if they’ve gotten displacement mapping with textures in the vertex shader working? I’ve set the basic-shaders #f directive in my .prc file and set the following profile directive in my shader program file.
//Cg profile vp40 fp40.

I have gotten this to work in pure C++/OpenGL, so I know it’s possible, but need help getting it to work in Panda. Also I am using 1.7.0

Thanks,
Murphy

Yeah, vertex texture fetch works fine for me using Cg. Note that the variable is named “basic-shaders-only”, not “basic-shaders”.
