Decimate modifier and color?

Ok so I made my model of a goomba from the mario game. I face selected the parts I wanted to color brown, but it keeps on coloring the whole model brown! I also want to make a pepakura model of it, so I tried to lower the polygons, but it said “modifier is disabled or returned error” How do I fix this? Also when I use the bevel tool, nothing happens. I selected the edges.

If you want to use more than one material on a mesh, you have to make material groups. ( see documentation ). You could also use vertex painting for different colors on different faces. ( see documentation ). I don’t know what a pepekura is, but if decimate isn’t working, check to see if it has any other modifiers, such as subsurf, that might be affecting it. As for bevel not working, I am not sure.
(edit) oh and btw, decimating an object destroys both material groups and vertex colors, so decimate first, not last.

Pepakura is a 3d model of your model in paper. You can download it for free. Where is the documentation?:confused: Ye kinda can’t do anything because I don’t know how to set material groups and do vertex painting

check the blender wiki for documentation.

Two cents here…
The Blender Wiki can be found at http://wiki.blender.org.

More specifically, here’s the manual page concerning Multiple Materials.
