Materials don't show up in final render

Hello all,

For some reason my materials are fine in render preview mode but not in the final render.

Any suggestions out there?


Based on what? A pointless screenshot? Supply a simplified .blend file that clearly illustrates the issue.

BTW, in case you’re wondering what those strange patterns on many of your objects are: Those are a strong indication of overlapping (co-planar) geometry, which can cause all sorts of render problems.
