Decal creates lighting artifacts on edge of meshes

When using deferred decals there are artifacts that are caused by the emissive color of the decal when viewing the decals from a low angle. These artifacts appear as thin lines on the edges of the mesh. This issue has not been labeled as a regression as this point
