PhysicsMesh

Meshes that represent the collision geometry of a model.

Display

• To toggle physics mesh display, select Display > Collision Geo.

Create

• Use the Model > Collision > Add Physics Mesh menu item.

Edit

• Meshes are accessible via the outliner, and are found under the Physics Mesh List item.
• Select a physics mesh item to edit in the Property Editor.

Data Structures

The vmdl physics mesh data looks like this:

CVphysicsMeshList m_physicsMeshList = CVphysicsMeshList
{
	CVphysicsMesh[] m_meshList = 
	[
		CVphysicsMesh
		{
			string m_meshName = "sdk_static_prop_physics"
			string m_meshFile = "models/sdk_static_prop/fbx/sdk_static_prop_physics.fbx"
			bool m_bUseExactGeometry = false
			bool m_bAutoMass = true
			float m_flMassOverride = 100.000000
			bool m_bOneConvexPiece = true
			bool m_bConcavePerJoint = false
			bool m_bSelfCollisions = false
			bool m_bForceKinematic = false
			bool m_bIgnoreScale = false
			bool m_bIgnoreSkeleton = false
		}
	]
}

m_physicsMeshList

A list of CVphysicsMesh elements.

Note:A vmdl can have multiple physics meshes. Mesh groups and LOD groups will refer to these meshes by name.

CVphysicsMesh

The data description of a physics mesh.

Attribute	Friendly Name	Description	Type	Default Value
m_meshName	Mesh Name	The name of the mesh	string
m_bUseExactGeometry	Use Exact Geometry	Do not convexify, instead use the exact geometry	bool	false
m_bAutoMass	Auto Mass	Calculate mass automatically	bool	true
m_flMassOverride	Mass Override	If automass is off, use this instead	float	100.0
m_bOneConvexPiece	One Convex Piece	Convexify as one object, if off generate multiple convex hulls	bool	false
m_bConcavePerJoint	Concave Per Joint	Create hull per joint	bool	false
m_bSelfCollisions	Self Collisions	Collide with itself	bool	false
m_bForceKinematic	Force Kinematic	Force physics object to be kinematic	bool	false
m_bIgnoreScale	Ignore Scale	Ignore Scale	bool	false
m_bIgnoreSkeleton	Ignore Skeleton	Ignore Skeleton	bool	false

Note:Force Kinematic, Ignore Scale, and Ignore Skeleton are possibly outdated and will not have a result on the compiled mesh
