Exhibit A: I call this the Loincloth-Mindy. Mindy is the main female character of Papa and let me promise you, she's not as permiscuous as this picture makes her out to be. Turns out she was in one spot in one frame and then 10 yards away in the next frame. Well the skirt I set up is attached to her waist and tried to travel at the speed of sound while holding on for dear life to her waist. I guess the path of least resistance is straight through her. (note: the actual math would have stopped, then magically moving at 490.91 mph then instantly stopped again. My diagnosis: fatal)
Exhibit B: I call this one Backless-Chaps-Papa. This is a tougher issue to pinpoint. I'm not sure exactly what happened, something about the way that he moved lead to this. The Skirt kinda explodes. It kinda looks like fireworks in my view (see below) but I try to smooth it out a little bit before rendering which is why the image above doesn't look anything like the one below but believe it or not they are exactly the same frame.
Here's a little render of what it Papa looks like after this issue comes up if I were to render out the entire shot. Of course, I'm not going to so you don't get a background. Mostly because rendering out the entire shot would take forever:
This is a solution that I found that makes the skirt a little less excited to be alive, and a little more like cloth should actually look like:
I leave you now with a picture of what I have named Papa-after-meeting-Liam-Neeson. Also a huge problem with the cloth appears. Don't worry, this happens off screen so it's ok that he looks like that.
