Create a Snail - Blender 2.5 - page 301

You Ready To Go Gung HO?
A Hotshot Challenge
Let's explore some ideas of how we can improve the result:
F Using the sculping tools available in Blender, we can work out the roughness of
the skin of the snail to replace the basic procedural bump-map that we applied.
F The lighing on the snail would look way beter if we get the lower part looking
darker, to beter match the global lighing condiions of the scene.
F As the snail is surrounded enirely by leaves, we can improve the lighing on it by
adding some lights that simulate the green light bouncing off from the leaves.
F The shape of the snail could be improved by adding some deformaion to its border;
changing the very straight shape that it has now. Once again, the sculpt tools can be
very helpful for this.
F The ulimate control for the shaders can be achieved by using hand-painted
textures that would require UV mapping to be properly set up on the surface.
