Hello Bob,
I have not worked as much as on the conversion yet so I do not have ideas
like you do. But I had a scene in mind and wanted to take some ideas from
Atmo.pov only to find out that Atmosphere is no longer supported. Most
likely I have to try it in V3.0 and at the same time work on rendering it in
v3.5.
I also rendered your scene you attached yesterday. The result is very far
from the original. I will get the one you attached in binaries and see how
it goes.
I also sent a cancelation for my previous post but it is still there.
