If i remember correctly, i've talked about target helpers in great
length with peter.
I've done bone setup utilizing parallel bone chains, targets, track
modifiers and different type of constraints that demostrate how you
can create automatic muscle bulge with carrara3. The same technique
could be applied to create secondary motions more easily etc. I
don't remember if i've posted in this group, but i'll try to dig it
up and post it here for studying. The problem is that i have to find
correct backup and i'm not the most organized guy in the world...
I normally never touch the bones, just targets. Bones track targets.
Also consider having other targets in front of the knees and make
knee bones point at those targets at one axis. Then group knee
targets and toe targets. This can solve some problems associated
with walk cycles etc. Or if ungrouped, it will allow you extra
control for knee position.
