==Run Havok Sim==
<br>
Toggles Havok physics, lighting, and vfx simulation in the Render window.

Some notes and tips:
* If you want the lighting and vfx simulations, but not the physics simulation (because you don't want objects to accidentally settle, etc.), use  [[Update_Lighting_and_Effects|Update Lighting and Effects]] instead.
* The physics simulation will only run on the objects that are currently selected; everything else will be frozen.
* Objects marked 'Don't Havok Settle' on their reference will not be simulated.
* Actors marked 'Starts Dead' will be simulated (ragdoll).
** If you Alt-Drag on a joint (such as a corpse's wrist), you can move that joint to fine-tune the position of the corpse. Note that the corpse will still re-settle in game, so you may not be able to achieve a very specific pose.
