I set a flythrough (camera move only) animation away over the weekend and it has just finished in time. Generally Im happy with the noise and look of it and finished in a reasonable time although some frames were taking 45 mins to render. But there are two major issues.
1. I set the cut off to be by noise level (5%) for consistent results but whilst for the most part this worked well I am getting some dropped frames in terms of sampling where the render time would drop by 50% and there is a noisy frame which really jumps out. I think this can be fixable by manually trawling for each frame and re-rendering those ones - its probably about 1 in every 100 or so. No reason I can think of and the culprit frames were on different PCs and the sequence will have been on the same PC as I had to manually assign chunks of frames and not use DR as Im a C4D user (latest beta).
2. Most problematic is I have very strong GI flickering on some of the surfaces - think incorrectly set up Vray of 5 years ago. I have set my GI method to animation (non flicker) with precision set to default one. All GI and other settings are default. I just changed the GI method and pressed render. I do have bloom and glare in the scene which I would like to keep in. Not sure if its related to that but I thought GI splotching wasn't even possible with corona?? Not sure how I would avoid this in the future as there are no settings to tweak for flickering as far as im aware. This may be C4D bug so I will post this there in the bugs section but wondered if it was more of a corona wide issue - perhaps related to the new sampling method?
I have checked for double faces and that shouldnt be the issue.
Unfortunately I cant post the results but might send it in to the brains. If anyone has got any ideas on what I can change for next time that would be helpful.
Thanks
