EditableMesh collision does not match visible geometry

Issue
Players collide with old geometry or pass through newly generated mesh areas.

Cause
Visual mesh edits and collision generation do not necessarily update as one cheap real-time operation.

Fix
Separate visual editing from collision strategy. Use simple invisible collision parts for frequently changing geometry, or rebuild collision only at controlled milestones supported by the current API. Avoid per-frame collision regeneration.

Verify
Display collision geometry during testing and walk, jump, and drive across every edited boundary.
