Collision

Collision lets runtime characters, navigation, or VR movement interact with scene surfaces. Third-person browsing does not require collision, but collision is needed for grounded movement and obstacle blocking.

Workflow

1. On the Create page, use Import Collision to import a PLY or OBJ collision mesh, or choose a preset and use Generate Collision to create collision from Splat Asset source data.
2. For interiors, choose a preset that preserves detail. Use the conservative general preset when unsure.
3. Enable Enable Collision on the LiSplatActor.
4. For diagnostics, enable Show Loaded Collision to inspect loaded triangles.
5. Use Export Collision to export a standard PLY triangle mesh.
