How to reduce unexpected ripple on 3d model?

[shmike]

Hi all,
When I loaded 3d module with CesiumJS in Chrome, I met an unexpected ripple issue, like showed in the image below. Do you know the root cause, or how to fix it? Thanks in advance

Welcome to the community!

Does the ripple effect only occur when viewing this 3D model in CesiumJS? If so, I suspect that you are noticing a Moiré pattern. Does this seem plausible to you? If so, I recommend that you check out out the following community forum thread:

@Bowen7 seems to be dealing with a similar issue. As I mentioned in his thread, I do not currently know of a quick fix to this issue. However, modifying the shadow and lighting settings may yield preliminary results.

Thanks Sam for your reply.
As you said, my issue is similar with @Bowen7’s issue (#16011). It may be a common issue. Could you or @Bowen7 or others look into it?
