Building Complex Game Objects - Beginning Game Art in 3ds Max 8 - page 81

Figure 4.1 Reference textures and polys are set up and ready for modeling.
Once the reference planes are in place, you should freeze them to avoid accidentally
moving them around.
1. Right-click one of the reference planes, open the submenu, and choose
Freeze Selection.
2. Save your file as Mustang _01.max. It is important to save often. I generally
use a numerical system to designate saved objects. You can use whatever
works best for you.
Note
The Save dialog box includes a button labeled with a plus sign that you can use to easily increment the
save number.
