I'm trying (and mostly failing) to do some basic animation stuff...so i've got a few questions.

1. i'm doing a basic skeleton, so i've got a hip, knee, and ankle joint. i created an IK handle from the hip to the ankle- how can i now rotate the knee (on the z and x axes i suppose) without it all collapsing?

2. my skin weights tool is really slow...is that just always how it is or could i be doing something wrong?

3. mmmm i forgot the last question so i'll have to come back another time.

sorry if they're stupid questions (yes, yes, i know there is no such thing), but what kind of newbie would i be if they weren't?
