		// This is somewhat arbitrary, but it allows the delta meshes to be moved aside relative to the base
		// meshes, as well as aligning the Pivot points to align the deltas and base mesh.
		// So:
		//	From deltaLocal to deltaPivot space = deltaVertToPivot * deltaLocalToVert // vertToPivot = OTM
		//	From deltaPivot to basePivot = skip (pretend they are the same).
