A fixed simple physics object, or a phantom volume, that its data marks as a wall for enemies (a navmesh carver, or solid with a group only enemies touch) adds its shape to the world's movement blockers, and takes it out again when it goes away. Only shapes the server knows are used; an unknown asset's stand in cube would be a guess, so it is logged and left out. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
