Title: Animation Flickering With Forest Pack
Post by: phymotion on 2019-12-09, 18:39:02
Hi Guys!

This is my first animation project with corona 4,I use forest pack and mengascans to creat the grass and the tree.
I have some flickering problem during testing.I konw my rendering passes are shot(about 5 with None Denoising mode).
but I don't konw if the intermittent disappearance of the plants also cause by this.
Would you please check my render setting screenshots? My CPU is AMD 3900X
My english is not good so the post may have some grammatical problem. I'm sorry about this
Thanks very much

I solved this problem.It was caused by the object exclusion function I used in the Forest Pack and I'll continued to test other flicker problems in the animation

The results is awesome!!
I finish my work with your suggest.No flickering now !
The only regret is that the Boom and glare cannot be added in time cause by Highlight damping。Anyway no matter about this
Thank you so much

Glad it helped :), you can try exporting Bloom and glare as element CShading_BloomGlare, that way you will still have control over it in post process, and you will be able to blur or denoise it separately in a pp software.

The suggestion regarding his case was mostly about highlight clamping he had many grass blades and a lot of glossy/reflective leaves that "sparkled" with motion, and thus creating firefly noise.

I suggested he use Highlight clumping values of 1.2 - 2.5  and to render with a noise limit of 3.5% - 4.5%, and it seems that these solutions worked fine for what he was experiencing on his animation.

If you are experiencing similar or different problems feel free to share your concerns and preferably a video/pictures showcasing the issue.
