I've got the skeleton's position set up, and all the verticies assigned now. All I need to do is pose, create a robot, and animate. Easier said than done.
I know I'm no expert at this yet, but you know you have to go into the hierarchy menu, create the skeleton and assign the verticies to the particular bones, then go Edit->Skeletons->Reposistion Joints to actually see the skeleton. Position, and then... Well, that's what I'm about to learn
I found all that at openfx.org, in the tutorials section; the simple skeleton one.
BTW: All of the joints were (for me) on top of each other, so I only saw the base joint at first, but if you move them around a bit, you'll see the rest.
EDIT: Looks like Dease beat me to it...
EDIT #2: Also, if your making a humanoid-type skeleton, make sure you don't do what I just did: switch the left and right sides. Try to move the left hand, and the right one moves... Grrr... This is going to take some work.
