I can just use the last public beta (A6.50.6) but it´s good to hear, that the transparency problem has been solved. I hope this overlay feature makes it into the next public update. Anyway, I was playing around with alphaBlendEnable & co. but it didn´t help. Most often my testcube just turned into something completely black.

@ xXx Guitar: I think it´s a very good idea, to implement an option for static lights. Makes this great shader even better .
