And sometimes it doesn't happen. Before today I haven't noticed it, though I
may have overlooked it. In earlier tests I was using a plain texture instead of
the "cells" pattern, and then I don't remember seeing it.
Just now I tried to reproduce it but I'm seeing a different baffling issue:
when I take out the "cells" pattern and replace it by a reference to a plain
texture, the parser complains that the "warp" modifier is not expected. See
attached.
Possible Parse Error: Unmatched {
"/Users/pkoning/Documents/svn/tajemnica/bumpmap.pov"
line 100
Parse Error: No matching }, warp found instead
