I am going to have a look at that but it seems most of the problems are based around lost settings for colour/texture/material between openings of Rayscaper.
The issue of Rayscaper not minimising is nothing new for me here.
The led lights in the kistchen of the my home renders was due to the glass cover of the unit becoming opaque. No way light gets through that. and later render has demonstrated this by castnig a shadow of the light fixture.
I believe this is nothing serious and only a matter of time. I know you are getting this right mate. Thanks for making this soon to be great program.
