Your tuto is perfect !

There is to much to learn in the same time, but I will see it again and again ...

One thing that I would have liked to learn is "How to build a glass" in the spline modeler.

There is only a few tuto about this modeler and it seems that we can do some very nice subtleties not easy to do in vertex modeling.

The lesson about the shaders and surrounding is also great, thank you !
