Hi volker! First that light is awesome. And the image its self is plenty fun to look at.
I wanted to point you to some more threads that may save you some time.
http://www.planetside.co.uk/forums/index.php/topic,9147.15.htmlI think that if you go through this thread and then a couple of others from ulco, than you will save some time. this is one of my favorite topics to watch so I look forward to hearing what conclusions you make and solutions you come up with.
Your renders are quite nice and I have read a bunch of your older threads going years back. So looking forward to see what you do now that you are back in the fun
Just posting because of your post in the other thread where you mentioned me. I wanted to make sure you had the work that others already did so you can build on that rather than starting fresh.... incase you did not see it I mean.
Ill tell you right now from my perspective, its all far to complex. Anything you can do to simplify any solution you come up with would be really nice to hear about.
