I am trying to create a GMOD Playermodel from scratch | Please help!

So basically what I am trying to do is I am trying to make CGI Star Wars Playermodels like this guy’s: http://steamcommunity.com/sharedfiles/filedetails/?id=700780874

I am trying to create more playermodels that this guy hasn’t finished but I don’t know where to start. I have been using google to try to find how to make a gmod playermodel but everything is not what I want. I need to know where to start from scratch in terms of creating a playermodel. Please help I am so confused!

This isn’t the right place for this post.

Take your shitty Starwars model question over to the fucking modelling section
