The ActivatePhysics trigger command was a TODO. The client activates or deactivates the object's physics component (LWOPhysicsSystemComponent::msgActivatePhysics, 1.10.64 0x00ccf970); the server now does the same to phantom physics: switching it off takes the volume out of the physics world (dpWorld::DetachEntity, without deleting it) and makes whatever was inside leave, switching it on adds it back and whatever is inside enters on the next step. This lets trigger driven volumes like the monument lasers turn on and off. Co-Authored-By: Claude Opus 5.5 <noreply@anthropic.com>
