Using it in Unity
Unity imports FBX and OBJ natively; for GLB/glTF add Unity's official glTFast package (com.unity.cloud.gltfast), which imports at edit time.
- Meshes named with
_LOD0…_LOD3suffixes get a LOD Group automatically on FBX import; otherwise add a LOD Group and set screen-size thresholds by hand. - Put the collision mesh on a Mesh Collider (enable Convex for rigidbodies) and keep its renderer off.
- Leaves: enable Alpha Clipping in the URP/HDRP Lit shader and render both faces.
- For the Terrain tree painter, save each tree as a prefab with a LOD Group. Dense forests benefit from GPU instancing, the SRP Batcher or the GPU Resident Drawer in Unity 6.
No SpeedTree importer or licence is needed.
