Hi there,

Is it possible to read the luminance value of an objects texture at a specified point using maxscript? I was hoping that I would be able to use a grayscale map applied to an object to control the script i am writing. Or is this only possible writing plugins using C++.

Thanks,

Nathan

you can read rgba data from the textures and even from a XYZ procedural map.

search the board it was discussed lately and the graet bobo ;) gave an example of the code to be used on XYZ.
