I found an AT ST star wars machine and this guy in red in the middle of the scene...

Re: Variation of brightness during animation

Hi, You said, render on CPU only. Is it BiDir? Do you use Metropolis? Have you tried Random? Avoid Sobol in your case. Yes, it's BiDir and it's always Metropolis... I'll try random but I'm afraid it wouldn't change anything. Additionally I'll try rendering without lux tonemapping - I'll postprocess ...

Re: Variation of brightness during animation

Hi, I don't know, but if you don't disable camera volume something like this may happen: Thanks for this links. It doesn't really explain why that happens, does it? Since everthing I do is CPU based, all GPU driver related issues can be denied. Toying around with the camera volume may lead to result...

Re: Variation of brightness during animation

Hi, I've tested the scene with disabled camera clipping. The result seems to be the same: Animation4.gif Again the belonging *.blend file with it's settings: Brightness_Variation_During_Animation3.blend Changing the material settings is not an option for me - finally the real part will be made from ...

Re: Variation of brightness during animation

Hi all, this are the proposed results. Doing simply the same renderings with a different random seed leads to this: - still strange bright/dark variations - which frame is bright and which is dark changes - noise pattern vary (as expected) This are the first 9 frames as single images as comparision....

Re: Variation of brightness during animation

Hello all, Thanks to all your reply. Can you upload some of the frames where it occurs (+ one before and one after, for comparison) and does it always happen at the same frames (if yes, which ones exactly)? Or is it random each time you render? I'm about to rerun the complete animation with a differ...

Variation of brightness during animation

Hi, I've rendered this object from different perspectives. The results looks like the light becomes more bright in some frames randomly. The estimated result ist a constant fall off for the side perspectives, but not such flash light. Animation.gif This is the belonging blend file: Brightness_Variat...
