Hello, thank you in advance for your attention!
I’m working on an Archviz project in Unreal Engine 5.5.4. Everything was going well until I started populating the scene with vegetation like grass, trees, etc., all imported from FAB.
When I began placing the trees after painting the grass using Foliage Painting, I noticed this bizarre noise in the shadows cast over the grass, and I simply can’t remove it or debug what’s causing it. I’ve already changed the lighting, anti-aliasing, and the grass material.
There are also other parts of the scene where strange flickering is happening, like on the stair railing of the house.
I suspect it’s some kind of Lumen or Nanite bug, but I don’t know how to fix it. Has anyone seen something like this before?
