How can i port League of Legends models into gmod?

i saw some LoL models on the workshop, and i want to know how they port them into gmod. (i don’t have knowledge into modelling btw)

If you saw them on the workshop they are already in gmod.

Also how do you plan to port models without knowledge of modelling?

1 Easy way is converting the format to dae with lol2dae ( for import
and then port as you would any other model. The blender importer didn’t work (this was 2 years ago though)
