I finally managed to get blender to export!
Now that I can see my animations instead of my characters exploding, I notice that my walking sequences are not very good.
I'm giving my first models away, mainly to ask if there are any good methods of making sure my characters will stop sliding as they walk. Any other suggestions before I go on to spending more time on higher poly models would also be appreciated. Also, I realize my generic person is backwards. I've just been using
yrotate object 1,180
fix object pivot 1
to get past this. In the future I will make sure to make people face forwards. And I'll try to make the lighting better on my future objects.
