Need Help With Creating Playermodel

Hi, I’m trying to set up a model for a player model, It is already rigged with its own skeleton it’s a .smd model and I followed this video for help: https://www.youtube.com/watch?v=aYnYWDALONI and I also asked for help on the TU discord and one person told me to delete the Vertex Groups for my mesh with “twist” but unfortunately, every time I try to import my model to the workshop it either turns into a big spaghetti-ish mess or I have compiling errors. Can someone maybe help me out somehow? I’m new to using Blender so I don’t know all the tricks and such. Thanks! here’s the model I’m trying to rig: bandicam%202019-03-28%2004-42-35-686|690x378
