Thanks again, TIG. It worked, and it was fun : )

Is it possible within the s4u-transformer-plugin to reduce the number of materials?

My previous problem got solved by the plugin suggested by Box (thanks!)
My new problem is now this;
I now have a bunch (5150 in total) of unique squares, and when i want to add the random texture i get 5150 textures! I used the s4u-transformer plugin for the randomized texture. It seemingly looks fine, but I can't work with so many textures. Are there other randomizing texture-plugins that work on components? Or is it possible to merge similiar textures? Since the model actually do not display more than a range of about 5-6 different shades.

I need to explode my components into groups, without making them joining the outside geometry.
