How to assign random textures to clusters?

[shushens]

Hi fellas!

I often come across situations where I have to texture a tree and all leaves are just one object. I can detach all polygon islands, select them at random, assign materials, etc. but that seems like a very unsophisticated approach. If I can assign every polygon island as a separate cluster in that object (I think there is a script accessible through legacy netview that does it), is there a way I can randomly assign textures from a pool to those clusters using render tree and simple expressions only (which basically means no major scripting)?

Thanks in advance!
