i need an shader which is able to assing random color from an gradient or image like this plugin in max does.

i got an shader which is able to genereate random color per polygon but in this case i got objekts with more faces. so it won't work.

any suggestions ?

edit:

i knew that the shader effektor in combination with an fracture object will do this. but it only works with a few elements.
