VRayAmbientLight and transparency

[robdeja]

Hi guys,

I am currently using VRayAmbientLight to fake gi in a sequence of shots and it's working really well in every way except for where I have transparent objects.
I have a VRayDirt shader in the ambientlight and where I have transparent objects in close proximity to other objects in the scene, I get very dark ambient occlusion where I would expect it to be bright (because of the transparency allowing light through). It does not respect the transparency at all and it makes no difference if I exclude the transparent objects from the VRayAmbientLight or Affect Shadows/all channels in the material.
I could render it in passes to get around this but I'd rather not if possible.

Any ideas?

Cheers,
Rob

Have you turned on the "Work with transparency" option in VRayDirt?

Best regards,

I would have sworn that that flag was enabled but upon double checking guess what!?

I should have known it was user error..

Thanks Vlado
