Basic shading, you know how to get decent shading using triangle normals. You can view normal maps for example, those you create using the transfer maps tool in viewport 2. Because different programs may use tangent space differently, normal maps. I dont think they can simply be multiplied by the projection matrix, because perspective division transforms things into clip space and as far as i understand, in this space planes that are coplanar to the image plane remain coplanar. Normal mapping without precomputed tangent space vectors. Implementation differs in that we sort between diffuse and spec.
