Hi everyone,

I have a custom node that takes as input a certain number of textures. At some point, I need to sample them all to disk. In case of a FileTexture, I just use the MImage class for loading it, and then later, saving it to disk.
My question is what do I do if the user creates, for example, a Ramp or a Grid texture and connects it to my node?

Thanks in advance,
Inos

MRenderUtil::sampleShadingNetwork, for some reason it requires Mental Ray to be loaded though..

So this means I have to first find the UV coordinates of all the vertices of the mesh in question, right?

Yes, but also this way you will get the color after with all color balance settings and stuff
