I can confirm the bug is there and I have created a bug report here: Grass tool culling broken - Programming & Scripting - Unreal Engine Forums
Grass Tool isn’t culling the meshes properly. Meshes happen to appear/disappear in quads instead of appearing/disappearing individually.
This bug might be specific to some specific landscape sizes only i.e in my case 1009x1009.
Repro steps:
- Create a landscape with the given settings as in the image.
- Setup a material with grass node.
- Use a mesh in grass node with high density.
- Reduce cull distance to 5000.
- Fly forward/backward to see the meshes culling.
Landscape settings:
Please don’t let this one be backlogged like the last few I’ve reported.
