VrayGlobalIllumination Element renders black sometimes

[squeakybadger]

Hi,

We seem to have a random problem where the VrayGlobalIllumination element will just render as solid black.

The main RGB pass will be fine, and all other render elements will render fine.

Resending the render will usually fix it, but I'm just trying to understand why it is happening (as we rebuild the final image using the render passes, the gi pass is pretty important)

I have nothing in the vray logs, or deadline logs that indicate a problem when rendering/saving files.


Any ideas?

Thanks.

Hi,

I'm not sure why this is happening but we can test your scene file here and try to reproduce the problem. Is that possible ?

Hi Tashko,

I've managed to isolate a scene file that does this repeatedly. I've sent the files and a more in-depth description of the problem to support so you can take a look at it.

Thanks.
