Raycast() -Casts a ray, from point origin, in direction, of length maxDistance, against all colliders in the Scene. Which would make sense, because RaycastHit in the case of Raycast DOES return the surface normal. Perhaps the returned UV coordinate is just the interpolated value of the three vertex UVs of the triangle. Your system that executes the raycast job must be annotated with UpdateBefore (typeof (BuildPhysicsWorld)) 2.
