Material ID from image.
Hello, I am currently trying to put multiple materials on a Fluid ball simulation and want the materials to come in batches (such as a circle of them). I have tried the random id and did not get my desired effect and was thinking maybe something with faces and material ids to spawn the balls onto or a image and each colour is a different id for the Multi-sub. Any help to get the desired effect would be much appreciated.

the attached image is the effect I would like but instead of just colour I would like them to be materials (ignore darker version of colours It is a rough mapping so not perfect just to show effect).
