WebThat question doesn't really make sense. Of course the mesh's vertex normals are in object space. The normals (together with the tangents) form the tangent space. So you can't define vectors in a space they actually define. The tangent space is only relevant when you do normal mapping. i.e. you apply a normal map texture to a surface.
