Evaluate WPO for Foliage(HISM) is based on Local Space？

• Create foliage type using the default cube mesh, enable evaluate World position offset in foliage type, paint foliage on the a plane mesh
• Make sure r.RayTracing.Geometry.InstancedStaticMeshes.EvaluateWPO 1 or -1; 
• Create a WPO material and apply to the foliage
• Change the material's offset value see the foliage shadow is changing but in very odd direction(actually in it's local space direction)
• Transform the offset value from Local Space to World Space in the WPO material, now the shadows are matching the foliage
