So I'm having a break through and a set back all at the same time with this animation stuff so i figure now would be a good time for a post. Maybe That will help me sort out my thoughts here.

I've been following the example code provided to us by Keenan. It's been a bit of a life saver as the fbx sdk can be a tough one to get through alive.  I did discover a flaw with Keenan's code however in that it essentially zeroes out anything that doesn't have an animation curve. For all intents and purposes this seems aimed at nuking out the dummy nodes. The problem with this is that a large number of the dummy nodes seem to contain some pre and post rotations that throw everything off a bit. when you zero this out it means your animations turn out wrong.

So now that I've figured this out I've run into a new problem. Every so often during the animation my guy decides to just flail his arm or twist his torso in a weird way. I can't exactly figure out why this is happening and I think It'll take a bit of digging to get it all figured out. I do recall one of my classmates mentioned a possible problem with the quaternions. I'll have to investigate.
