Hi everyone,
I’m running into a wind animation issue with my vegetation in Unreal Engine and I haven’t been able to resolve it.
I’m using SpeedTree assets (imported from SpeedTree / SP) with the default SpeedTreeMaster material. When I place my trees as regular Static Mesh Actors, the wind animation works correctly (trunk stays stable, only branches and leaves move as expected).
However, when I place the exact same meshes using:
- Foliage Tool
- PCG (Procedural Content Generation)
the wind behaves incorrectly.
The problem:
The entire tree starts deforming from the base, almost like a wave passing through it.
The trunk is no longer stable — it bends and moves unnaturally, as if the whole mesh is affected uniformly.
Any help or direction would be greatly appreciated. Thanks!
