Shadow jitter problem in large scenes

[wddl]

The 3D model is placed in a large world where the shadows shake at a Specific camera height. And this phenomenon does not occur in a small scene. How should this problem be solved?Thanks

There's been some work on shadows recently, make sure you're using the latest main branch or wait for a more recent build of Filament to release. Can you post a video of the phenomenon? There are a lot of parameters in ShadowOptions that you can try adjusting. In particular, stable might be useful.

thanks! stable is useful, but it has a limited effect, and a slightly larger scene is not. I put the model on the scale of the earth. Recorded a video and sent it out. There was a serious problem at a specific camera height.

I haven't tested the latest version yet

@pixelflinger Might have some ideas for you to try. But definitely first get a recent build.

Thanks! I'll test the latest version

@bejado I have tested version 1.43.1, but the problem still exists. It's strange that the shadow effect is fine when the camera is at a far distance, not in the middle, and in close range the effect is fine.
