Vray Light outside windows appear opaque in alpha channel

[j.galang]

Dunno if this has been asked before, but when i place planar vray light outside my windows it blocks the alpha channel of the window. this means i cannot get a correct alpha channel to matte backgrounds outside the window. i did have the light set to invisible, but cannot find any other parameter to adjust. any advice would be great. thx.

Setting the light to invisible works fine here.

Have you set your glass material to affect alpha? which VRay version are you using?

I guess i will have to troubleshoot a bit more, using 1.5 RC3. Yes i have the glass set to affect alpha.

There is a problem with multi-subobject materials and affect alpha/shadow in RC3:

If it's your case, you can try just to detach your glass part and apply to it a simple VRay glass material.

I can't test RC3 here so I don't know for sure if this is your problem.
