Ok, so several passes in the cloth room have shown me a few things about using dynamic cloth in an animation:

1. Start with zero pose, and have the first pose of your animation start between frame 5 and 15.

2. The first 30 frames of your animation are to drape the cloth, so you are going to have to trim them in post.

3. The cloth will drape properly and follow the character throughout the animation, regardless of the length of the animation if you follow point 1.

And I can animate dynamic clothing. It just takes a bit to figure it out.

If I had a nickle for ever time a woman told me to get lost, I could buy Manhattan.
