Tutorial: Creating a low-res hand
You can use the ProOptimizer modifier to dynamically dial down the resolution to exactly what you want.
In this example, you use the ProOptimizer modifier on a high-res hand model created by Viewpoint
Datalabs. The hand weighs in at 2,906 polygons, which is a little heavy for any game engine.
To create a MultiRes hand, follow these steps:
1. Open the ProOptimizer hand.max file from the Chap 26 directory on the DVD.
This file contains a simple hand model.
2. With the hand selected, choose ProOptimizer from the Modifier List to apply the modifier to the
hand model.
3. In the Optimization Options rollout, enable the Protect Borders option, the Merge Vertices option
with the Threshold to 0.05, and the Merge Faces option with the Threshold set to 0.5. Then click
the Calculate button.
4. Create a copy of the hand by holding down the Shift key and dragging the hand to the right. In the
Clone Options dialog box that appears, select Copy, name the clone Hand – Lo, and click OK.
5. With the cloned hand selected, set the Vertex % to 10.
Notice that the number of faces has dropped from over 2,906 to 286.

Figure 26.10 shows the results of the MultiRes modifier. If you look closely, you can see that the hand on
the right isn’t as smooth, but it still looks pretty good and the game engine won’t complain.
