Hello, for my final major project at college I'm aiming to create something similar to the music video for wide open by the chemical brothers. I'm at post production stage now and I've finished all my motion capture stuff and I've started working on how to put it onto a model. I can't see anything wrong with the skeleton so I'm at a loss as to why the model is deforming so much. I also don't have a ton of experience in houdini, so any tips or suggestions would be really appreciated. I've linked the hip file for anyone to take a look at.
Thanks in advance!
