Model and Shade your Hero/Heroine - Unity 3 Game Development - page 95

4. Then, we will apply all of them together to create our custom toon shade style, as
shown in the following screenshot:
What does it do?
In this project, we will start with opening the character model in 3D Studio Max, set up the
unit scale and rotaion, export it as an FBX ile, and then put it in our Unity project. This will
give us a basic understanding of how to export the FBX file format from 3D Studio Max.
Next, we will create our first shading language by using the surface shaders, which are
included in Unity 3.0.
"Surface shaders in Unity is the code generaion approach that makes it
much easier to write lit shaders than using low level vertex/pixel shader
programs, which is much more complicated. However, there is no easy
way to write the shader programming, we sill have to write the code in
Cg/HLSL."
