Lineforce help - ODM

Help and Feedback Scripting Support
#1

I been trying to create something called ODM/3DMG from an anime called Attack on Titan. However, I am struggling on the system someone referred me to, Lineforces.

I’ve parented and assigned a lineforce and it’s attachments, however it just doesn’t work and flops the character. Anyone know why?
