Public Attributes
xiiMat4	m_GlobalTransform = xiiMat4::MakeIdentity()
	The global transformation matrix for this mesh instance, used to transform the vertices of this mesh instance from object space to world space during rendering and culling operations.
xiiUInt32	m_uiObjectId = 0U
	The object ID for this mesh instance, used to identify this instance in GPU-driven rendering techniques such as mesh shaders or compute shader-based rendering, where the object ID can be used for per-instance data lookups, material selection, or other instance-specific logic during rendering.
xiiUInt32	m_uiMeshletOffset = 0U
	The byte offset into the meshlet buffer where the meshlet data for this instance begins, used to identify the starting point of the meshlet data for this instance in GPU-driven rendering techniques such as mesh shaders or compute shader-based rendering, where each instance may reference a different subset of meshlets for rendering.
xiiUInt32	m_uiMeshletCount = 0U
	The number of meshlets referenced by this instance, used to identify how many meshlets belong to this instance for rendering and culling purposes in GPU-driven rendering techniques such as mesh shaders or compute shader-based rendering, where each instance may reference a different subset of meshlets for rendering.
xiiUInt32	m_uiMaterialBase = 0U
	The base material index for this instance, used to identify the starting point of the material data for this instance in GPU-driven rendering techniques such as mesh shaders or compute shader-based rendering, where each instance may reference a different subset of materials for rendering.
