Whenever I try to render one of Chris' demo files, I get the following
type of error:

Scene3.inc:32: error: transform identifier expected but { found
instead.

What should I try?

Thanks,
Glen Berry

Oops!
The compile I was using also incorporates my transform patch, which 
allows transform {...} blocks to be used in objects, instead of just 
"transform IDENTIFIER". The demo files use the new syntax, they began as 
test files for it. I am not surprised Nathan didn't catch it when he ran 
the files, since his compile probably also incorporates the transform 
patch...
Just change the files so "transform {IDENTIFIER}" is changed to 
"transform IDENTIFIER" and so the wrapping "transform {...}" is removed 
from statements of the "transform {rotate|translate|scale|matrix}" type.

In other words, change this:
transform {aDeclaredTransform}
to this:
transform aDeclaredTransform

and this:
transform {
    rotate < X, Y, Z>
    scale < X, Y, Z>
}
to this:
rotate < X, Y, Z>
scale < X, Y, Z>

Thanks for explaining that for me. I have now rendered some of the new
demo scenes sucessfully, but each time I render a scene, I have a
".tpn" file left in the same directory as my output image. It was my
understanding that ".tpn" files are temporary, and should be
automatically deleted after the render is finished.

For the record, I am using a DJGPP compile, and running it under
WIN95. My output format of choice is ".PNG" - I haven't tried yet to
see if the problem is isolated to PNG output only, but I'll let you
know later if it also happens with TGA output.

Later,
Glen Berry

As I recall, this is a known bug: the temporary file is not deleted if 
PNG is used. I think there was another problem: the PNG file is not the 
post-processed version of the image, although I am not certain of this.
If you use TGA or some other format, it should work fine.

There is a bug with POV's PNG code, which causes this problem in post
processing.  It will be fixed when we get around to releasing version 0.5.
Until then, you'll have to use a different file format.  (And on the Mac,
Pict is broken in 0.4, too.)
