I’ve been working on an open-world level in Unreal Engine 5. The issue is in the early-access version, as well as the preview version and I have not been able to resolve it.
As you can see in the video the grass is flickering like crazy and there is also some flickering in the trees. I’m using the recently released megascan trees, which should be good to use from the go.
The issue persists when swapping out the grass foliage meshes. I suspect that it has something to do with Lumen and raytracing, however I am not an expert on the subject and the problem was still there when I tried it out on different computers (all of which had RTX graphics cards).
Did anyone run into similar issues? Help would be greatly appreciated!
Have you tried to switch to Scalability: Cinematic and in the Project Settings to activate Lumen as Global Illumination Method and activate Hardware Raytracing (if your GPU allows)?
