With the examples/samples I've copied from the books, if I use the view matrix it does not work. The light goes to the wrong side, the normal map is a mess, etc.
If I use the modelView, I get a bit of movement, which is noticeable on the specular/shininess. But Is not problematic, for now.
I was trying to use the OF shader from the ofMaterial so that I could apply mappings and other stuff to learn and compare results. Copy/paste the vertex and just the spotlight from the fragment, double checked uniforms and seem to be all okay, but this happens :
That weird colors on the right, caused by the diffuse. Do you know why?
