Thanks for testing.
On remaining empty. My only guess is perhaps there is no radiosity set
up in the scene? It "might" be with certain scenes default settings do
I'm no radiosity expert, but I think in playing yesterday I picked up
there is some sensitivity to scene scale. Meaning any given collection
of radiosity settings might work better with a scene covering a range of
+-10000 than one within a range of +-2 (1). Maybe I'm getting fooled /
fooling myself - more work necessary to be sure.
If you have time to post more on the segfault when RadSamples exists, it
might be useful when I look at fixing this for povr. In any case, I'll
keep what you posted in mind.
