Thanks for comments, well in fact the tail is smooth but I used a texture plugin to achieve this look.
I’ve used some reference photos and have tried to achieve a look as close as possible to them.
For the Blender guide text, the problem is that I built a book model that was too much subdivided and that’s what caused the trouble with UV mapping.
For the books nothing difficult : a simple uvmap on as simple book mesh.
And oh, the writings on the page are a piece of code from the Yable script
I’m sure you can do that.
The head of the rat is very great !
So i’ll say the same things that everyone here : the tail is a little weird, and I think CurtisS is true… Shadows are missing on this pictures…
