p3_prop_physx

p3_prop_physx is a point entity available in Postal III. It is used to add models that utilizes the Nvidia PhysX physics engine.

p3_prop_physx entity with Postal Dude model (one of the only cloth models that utilizes PhysX physics engine).
Left - PhysX disabled; Right - PhysX enabled

p3_prop_physx after being interacted by the player (Postal Dude), by walking or kicking the cloth model itself.

This entity is designed to work with certain cloth models, such as the one used for Postal Dude's coat. It also does not interact or react with props using Havok physics, grenade explosions or bullets. Disabling PhysX using physx_enabled 0 or launch argument -nophysx will replace the material of the "cloth" models with a template texture (such as template_body for Postal Dude's coat) and disable the PhysX physics engine (Entirely disabling it if the -nophysx launch argument is used).

In the case of the Postal Dude model, disabling PhysX will cause the game to load a fallback version with preset animations.
