Hi. thanks. I’ve tried this out but I think this is a different issue. It’s only the static mesh foliage instances that have this problem - the static meshes are working fine. The middle tree in below vid is a static mesh - behaving correctly - the two either side are static mesh foliage instances of the same static mesh but with strange effect/animation. If I disable wind or nanite this issue is resolved.
So the problem seems to be that nanite may struggle with animated static mesh foliage instances? I’m not sure. Any further ideas on this? Ideally I’d keep nanite and wind on the tree. Cheers
