Need help with porting big model to Garry's Mod

Hello guys. I have model from one game and it’s very big. Isn’t it possible to keep its size and rig it somehow to make it work in Gmod? Thanks for any help!

Any size can be imported into the game I believe. If you wanted this model to be rigged and imported, you’ll have to figure out how to import playermodels. Im sure that theres millions of tutorials for this as the steps and stages to importing p.models are quite long and fiddley but if you have a little snoop around, I’m sure youll find something
