Is there a way to make the red tail-lights shine a little less
brightly?

The easiest way to fix that is to modify the light sources in the .pov code.
They should probably be less bright, you can multiply the whole RGB triple
by a constant less than 1:

... 0.4 * <r, g, b>

It would also help changing the 'fade_distance' and 'fade_power' to make
them not shine so far.

Or you could change them to 'spotlight' and adjust the 'falloff' value
instead. I think that's what I would do.

Thank you, Anders, I think that should do it. But the thing is, in LDA I try to
do everything before running it all trough L3P. Adding post-processing to the
steps already involved in LDA is not very appealing to me. And after the most
unfortunate ban of inline POV code in official LDraw parts, I almost haven't
touched any POV code by hand. Let's see if I can create a number of light
objects with inline POV code - or maybe let LDA create them inside the LDraw
frame files! At least I have some options to experiment with (instead of
sleeping tonight...).

Thanks, Anders

Hi Tore,

Try something like the following

(...) I just did before I read your post! (Just called it test.dat instead...) And it really works, the problem is POV will not inline the light into the position of SOFLIGHT.DAT but rather <0,0,0> of the POV world. This makes it more complicated, (...) (17 years ago, 25-Mar-07, to lugnet.cad.ray)
