The Blend option,which is often the most
useful, causes weight values to fade steadily to 0 within the ???capsule??? (like the Subtract setting),
but sets all values beyond the threshold distance to 0 (like the Clip setting).
Apply Weight Maps
Exercise 12.5 instructs you on the method of weighting. This process is done in Modeler
and enables you to tell a bone to control a specific area rather than the entire object. For
example,with weighting,moving the lower leg would not affect the upper area of the penguin,
as it did earlier in Figure 12.25.
Bone weights enable you to specify regions of influence.Much of the time when creating
character animation you??™ll be building your model from the ground up, and you can
assign weight maps as you go.However, you can also use existing models from a previous
project, from another artist, or perhaps from this book??™s DVD.

Exercise 12.5 Creating Weights
1. Open Modeler and load the Penguin_toWeight object from this book??™s DVD
(Projects\Objects\CH12\Penguin_toWeight.lwo). Figure 12.32 shows the model
loaded. Press a to fit the model to the view to match the figure.
