Hey! Not entirely sure about the fix, but here are a few things you could try:
- Give this a shot:
r.Raytracing.shadows.enabletwosidedGeometry 0. Even though it doesn’t seem like it from your gif. - Make a backup and start messing with the material setup/settings. Turn off the wind, tweak things around – sometimes it magically sorts stuff out, or at least points you in the right direction.
- Disable/enable anything related to lights, shadows, and related elements.
- Drop that tree into a blank project and see what’s happening.
- If movement isn’t crucial, export it as a mesh, then reimport it back into UE. Try to merge, cut all primitive stuff.
- If all else fails, consider changing trees. Sometimes, when time’s ticking, finding a workaround is the way to go.
- Last one form me: Get rid of the leaves parts and replace it with others that work (from Quixel for example). Good luck!
