animation prepass problem

@glorybound

Thank you for your quick answer Jackie,

I guess there is something in the workflow you are using for irradiance map precalculation process . Would it be possible to send us two files, one set for GI precalculation and second setup for the rendering stage? We will try to replicate the issue here and find out what cause it.

Do you use a V-Ray Embree for this project?

Actually there are a lot of splotches visible in all parts of the room, but the ones on the Window blinds are in very weird shapes.

Does it help to clear the splotches when you run a small region render?
The best GI approach for this case would be Brute force / Light cache (use camera path), I think. There is no need to precalculate GI maps and you can directly render the animation frames through Backburner using all available render nodes.

ok, please give your email, i will send the file to you now.

i didn’t use Embree in this project, because i am not using VRay 3.0, i am VRay Adv 2.40.04 user

Regards,
Jackie
