Strong artifacts with dome light and saved LC

V-Ray V-Ray for Maya Issues

Hi,
when rendering with a saved LC (mode “From File”), I get very strong artifacts. When rendering with mode “Single frame”, no artifacts appear. This only happens when the dome light attribute “Dome Adaptive” is on. The artifacts are stronger, if there is a small light source in the HDRI, like a sun.
You can see the error clearly in the two renderings. I have alos provided a scene file for further analysis.

Cheers, Florian

I think it could be improved? but I think the idea of adaptive dome light is that you don’t need to store LC to file when you use the adaptive dome. I honestly don’t use it because of other issues it has.

It’s a bug that’s on my “to do” list to resolve ASAP. In the meantime, the solution is to not use a saved LC; apologies for that.

Best regards,
