Why?
Fingers? Why fingers and not an individual finger? A lot of this depends
on the needs of a game and a model. In our game the character will
generally be holding a weapon or perhaps pressing a button. This means
that the index finger and thumb would need to be separately articulated,
but the middle, ring, and pinky fingers would not—they would generally
function as a unit. This might be different for different games; the hand
would be rigged in a different way if all the fingers needed to articulate
separately. But to add joints to the ring and pinky fingers would be
another eight joints (per hand) or 16 added joints for the model;
considering that the entire rig now is 25 joints, rigging those extra fingers
is a significant cost.
Step 49:
Create a string of joints for the pointer finger as shown in
Figure 10.22
. Build this chain off the wrist (from either side- or front-
view panels) and remember to tweak their positions in front-side- and
perspective-view panels to get their positioning right.
Step 50:
Create a string of joints for the thumb as shown in
Figure 10.23
.
Again, build off the wrist in front- or side-view panels, and go back and
adjust later with just the Move tool.
