Title: Flickering Lights
Post by: Otuama on 2024-05-12, 00:00:03

Hi all,

I'm rendering an animation of a data centre.

It has quite a few lights in the scene and my tests have shown that some lights are flickering.

I'll post a proper example when more frames are rendered but thought I'd post this now to try to determine a solution.

I'm using UHD cache. 

It was flickering with Adaptive Light Solver (ALS) on.

I'm doing a test with ALS off

And another with ALS off & environment sampler set to Precise (rather than adaptive).

Flicking through the frames it looks like I'm still having the issue.

Does anyone have any ideas how I can stop this?

Thanks


P.S.  Images don't seem to be working so I've posted a link of what it looks like

You have to precalculate uhd cache for animations. Here's a link with more info: https://support.chaos.com/hc/en-us/articles/4528617365649-How-to-use-the-UHD-Cache-for-animations-and-stills-in-Corona-for-3ds-Max

If you don't want to play around with that. Then just switch to path tracing, slover but less problems.
