MR Opacity problems and billboarding

[Brett]

Hey Guys,

 

I am having problems billboarding in MR. I'm using a HDRI exterior dome light. I'm also using a dome with my environment on it as this will be an animated scene. The HDRI dome has visable to camera turned off so that you can see the environment dome beyond and not the ugly HDRI image. When the opacity part of a tree is in front of the environment I get a white area where it should be opaque. If I move the environment dome in front of the HDRI dome I loose the lighting from the HDRI dome but it solves the problem with the opacity channel. Any chance I can have the best of both worlds? - If not I'll just suck it up and buy VRay cause I'm tired of dealing with MR shortcomings. I am sure many people have used this same method so hopefully someone can give me a tip.

 

Also I have the same problems if I use the Lume facade shader.

 

Thanks

Have you tried UNchecking the 'Affect Environment' option in the exposure control?

Thanks for the reply...

 

Do you mean under Environment and Effects/Exposure Control dialog box? I do not use exposure control at all - it is turned off and "use environment maps" is gray.

 

Thanks
