Mesh

[Mesh](API\Plugins\MutableRuntime\MuR\Mesh) object containing any number of buffers with any number of channels. The buffers can be per-index or per-vertex. The mesh also includes layout information for every texture channel for internal usage, and it can be ignored. The meshes are always assumed to be triangle list primitives.

Remarks

Mesh object containing any number of buffers with any number of channels. The buffers can be per-index or per-vertex. The mesh also includes layout information for every texture channel for internal usage, and it can be ignored. The meshes are always assumed to be triangle list primitives.

Variables

  Type Name Description
Public variable TArray< Ptr< const PhysicsBody > > AdditionalPhysicsBodies Additional physics bodies referenced by the mesh that don't merge.
Public variable TArray< uint16 > BoneMap Array containing the bonemaps of all surfaces in the mesh.
Public variable TMemoryTrackedArray< FBonePose > BonePoses This is the pose used by this mesh fragment, used to update the transforms of the final skeleton taking into consideration the meshes being used.
Public variable TArray< TPair< EMeshBufferType, FMeshBufferSet > > m_AdditionalBuffers Additional buffers used for temporary or custom data in different algorithms.
Public variable FMeshBufferSet m_FaceBuffers

Public variable Ptr< const PhysicsBody > m_pPhysicsBody  
Public variable Ptr< const Skeleton > m_pSkeleton This skeleton and physics body are not owned and may be used by other meshes, so it cannot be modified once the mesh has been fully created.
