Shadow flicker

V-Ray V-Ray for 3ds Max Issues
1

Hi,

I have problems with strongly flickering shadows.

max 2021, V-Ray 5
- maxstart.max deleted
- after restart of max switched from arnold to vray

V-Ray Settings:
Default, Buckets, LC-Preset Animation
Result:
KaFa_max2021_Vray5_DefaultSettings.mp4
Loop6Frames_DomeL_Tex_BFLC_VRayDeflault.mp4

I only get good result with local subdivision (V-Ray4, Global DMC).
Result:
KaFa_max2019_Vray4_DMC-LocalSubDiv.mp4
Loop6Frames_DomeL_Tex_BFLC_localSubDiv.mp4

Could you send the scene to support@chaosgroup.com so we can take a look? Mention this thread in the e-mail along with your V-Ray, host platform versions, and a log from the rendering.

did you find a solution to this?

No scene was sent for investigation, I’m afraid. If you have a similar issue, do write to the mentioned address with the necessary information.

Was there any conclusion, I have the same problem. Thanks!

Without a scene, we can’t figure things out: they may be obvious to some, but they aren’t always so to us.
It’d be good if you could send one to support.

I cannot really send you the project files. Here is the problem: Dropbox - Error - Simplify your life

Light cache, gpu render with 3 gpus. vray default denoiser, its not turned on in this video, but produces the same flickering

looks like light cache to me. try bf+bf first.

GPU-calculated LC?
That’s still very WIP.
Try the CPU LC if you haven’t yet, it ought to fix the kind of issue you see.
