I have this weird visual glitch with nanite and lumen


I was working on level design, adding nanite meshes and lights and it was all working just fine. I made that stairs area and now I have this weird glitch there, and only there. Any ideas what is going on?

It’s VERY hard to see.

Can you add more light to the scene?

That looks like a screen-space issue, not a lumen or nanite issue. When during the process of making the stairs did the bug start?

I also think it’s something about screenspace because of the way the artifacts look. Disabling reflections does not remove the glitch.

I have narrowed down the issue. I have these crystals that have a point light in them and their radius overlaps. If I reduce the radius then the issue disappears. I can reduce it and fix it, but I am curious why this is happening. Did i reach some light limit for the static meshes in this area?

With the fragmented nature of that issue, I’m honestly not sure what it could be. What happens if you disable volumetric fog? If you’re using it, that is.

I have found the issue. There were too many overlapping lights. I knew I had to reduce the radius and reach to lights, I just forgot. So this was the fix.

Overlapping lights? I’m really surprised that that is an issue, as differed shouldn’t really have those kinds of limitations in most cases.
