Yup. Whatever texture you want to use in the shader needs to be part of

to use it.

I tried to add the texture as a chunk to my material, but I still couldn't
get the shader working correctly. I added the texture like this:
SimpleMaterialPtr simpleMaterial = SimpleMaterial::create();
beginEditCP(simpleMaterial);
simpleMaterial->addChunk(shl);
simpleMaterial->addChunk(texture);
endEditCP(simpleMaterial);
Where shl is a SHLChunk object, and texture is a TextureChunk object.
I took a look at the testCGShader.cpp (located at Source/Contrib/CGChunk),
and the only difference with my code would be that in my shader, the uniform
sampler is declared globally to the shader, whereas in testCGShader it's
declared as a parameter to the main function.
Thanks for your attention,
Theo
