I tried to rerender abyss.pov by Gilles Tran at 3000x1200, but after a few
hours I had to stop the render because I noticed that the texture looked
somehow wrong. Either it's got something to do with the scene file (but
I don't think so) or with the cells pattern. In that case I think the scene
should be updated. Here follow two images: image1 was rendered with POV 3.5
b2, whereas image2 was rendered with POV 3.5 b1. The differences are clearly
visible.

You're right. Definitely appears changed from previous renders. Looks like
a filter or transmit problem.
And now I see it probably is, having now exchanged the word Clear for rgbt 1
instead. Clear is rgbf 1, I've added #declare Transparent=rgbt 1 to my
colors.inc just now so I'll remember this.
Could the "radiosity always on by default" have caused such a thing?

Sorry I missed your post... I was actually trying to fix that yesterday night.
It looks that the main culprit is the normal statement, though I first thought,
like Bob H, that it was a transmit/filter problem).
The normal uses the cells pattern, which has been fixed in several ways for this
release. As the doc says that cells is not suitable for normal anyway, I just
dropped it and it works fine. If anyone has a good replacement for a hull plate
normal, it could be interesting.
Looks like I really have to investigate the text distortion problem, BTW.

From looking at the image, the text distortion actually looks like it could
be caused by transparent cells, the distortion looks like the letters
extruded into the hull. Perhaps some of the cells are picking up a
transparent texture

I saw that in the docs and think it's either misleading or needs more
explanation - surely in the case of hull plate normals the cells pattern is
perfect ? If not, why not ? Checker, for example, is similar to cells (no
smooth transitions), yet it isn't stated to be unsuitable in normals...

The holes removed in 'HalfSubBottom' cut boxes out along the line of the
text.
Hole=box{<-6,0,0>,<1,0.05,0.5> translate y*0.1}
This is what we are seeing here, the text actually isn't distorted.
Either remove the holes, change their position or change their shape/size.

Oooh, many thanks. Bad bad bad holes ! They were a leftover from a previous
version I think, not very useful anyway. I'll fix that.
