There was a topic on CG Talk written last year about sampling 2D textures. Pascal at Double Negative written an node to sample a color at point using:

renderUtil = OpenMayaRender.MRenderUtil
renderUtil.sampleShadingNetwork(....)

You can find the download here:

I written a custom node to sample the color at a given UV for deformations... it works on all 2D textures except for files, movies, and for some reason checkers. I can believe the files and movies... will need to use MImage for the files.

Anyone have a clue why checkers don't work?
