Strange shadow + GI bug

(1/3) > >>

barnabash:
Hi there! I am having a strange bug and I would really appreciate some help as I tried many days to solve it and failed.

I have an image sequence of an interior with HDRI exterior lighting, some IES lights, some rope lights, some mesh lights etc. Thes scene is fairly complex but nothing too crazy or something I haven't done in vray without any issues before.

I want 7 shots, and the way I do it is that I animate the camera and then render the animation sequence and this seems to be the root of the problem.
From the 4th frame onward, the shadows and GI are messed up. If I render the exact same frame as a single frame, everything looks good, the image is perfect, but if I render the animation sequence, after a couple of frames the GI and shadows become messed up.

Any idea how to resolve this other than the obvious "ditch the animation sequance" solution?

I attached a small example of the bug. 1st image is wireframe, second is when I render as a single image, the third is the bugged when I render as part of an animation sequence.

romullus:
I think there was a similar case recently and the solution to the problem was to disable adaptive light solver (or maybe it was adaptive environment sampler, or GI solution adaptivity - can't recall exact setting). Either way, you may want to give it a try and see if that helps.

barnabash:
I think the problem is solved, thanks a lot romullus! The solution seems to be unchecking "Enable adaptivity" under Adaptivity and Denoising.

romullus:
I'm glad to hear that the workaround has worked. I think Corona team may want that scene for testing purpose, since they definitely will want to fix the issue properly.

barnabash:
Looks like I spoke too soon. On the hiogher resolution render overnight the same problem came back :(

I'll try disable other adpativity settings.
