Initializes the physics mesh of the entity from a triangle soup defined by a table of vertices. The resulting mesh is hollow, may contain holes, and always has a volume of 0.

While this is very useful for static geometry such as terrain displacements, it is advised to use Entity:PhysicsInitConvex or Entity:PhysicsInitMultiConvex for moving solid objects instead.

Entity:EnableCustomCollisions needs to be called if you want players to collide with the entity correctly.
