Topology in deformation

The topology of a model greatly affects its deformation. While this leans more toward modeling rather than rigging, it can be really helpful to know that there are ways of achieving better deformation that you might not have expected. Figure 8.3 shows some good basic examples of how different topologies can affect the result of the deformation:

The next screenshot, Figure 8.4, shows a potential solution to achieve decent deformation on a bend:

You can mix these examples (and many other ideas) to combine their effects, and an experienced artist can integrate these basic principles into a dense and complex model.

Sore spots such as elbows and knees are prime contenders for topology bends, but you need to be expecting issues in advance of making the character because it affects the way the model...
