Sorry again. I wasn't smart there. Of course, default 'diffuse' finish should
still show shadowing when a normal statement is used, regardless of a finish
statement even existing or not.

Only way it wouldn't, that I can think of, is if scale is messing with the
normal. Or bump_size itself is affected in a bad way somehow.

Beyond that, I'm back to wondering about the program. I checked versions 3.7.0
and 3.7.1.rc1 and image_map doesn't remove a surface normal in my testing for
that. All okay here, anyhow.

Here we are approaching 60 messages in this thread, must be an answer to the
mystery... thing is, no one else has had the same thing happen yet, except for
finding trouble with low contrast, dark image/bump maps.

And now the green balloon render lacking bumpiness only makes the mystery more
so one.

Never give up hope, but this is a tricky thing for whatever reason.

Bob
