Summary

Let users select props, release them into simulated gravity, then commit or cancel settled transforms.

Why

Physics placement is a practical prop-authoring workflow that uses the existing Avian/PIE foundation without manually tuning every transform.

Implementation notes

Add tool for selected static mesh/prop actors with collider data.
Run temporary simulation preview in edit context or controlled PIE-like sandbox.
Commit settled transforms or cancel back to originals.
Group the whole settle session into one undo entry.

Acceptance criteria

Selected props can drop/settle onto colliders.
User can commit or cancel without corrupting authored state.
Tool reports missing collider/rigid body prerequisites.
Undo restores pre-placement transforms.

Tests/docs

Simulation fixture tests where practical and transform restore tests. Update README/docs controls.
