 1. Add a new layer for the planes created by Spatial Processing. Mixed Reality Toolkit's **Apply Mixed Reality Projcet Settings** automatically addes a new layer **31:Spatial Mapping**. <img src="/External/ReadMeImages/MRTK_SurfaceMagnetism1.png" width="550"> <img src="/External/ReadMeImages/MRTK_SurfaceMagnetism2.png" width="300"> <img src="/External/ReadMeImages/MRTK_SurfaceMagnetism3.png" width="550"> <img src="/External/ReadMeImages/MRTK_SurfaceMagnetism4.png" width="300">
