There's a plugin called 'Blender Source Tools' that allows for importing/exporting Source models, but you'd have to decompile them using another tool called 'Crowbar'

hey so i just saw your halo 3 MP spartan workshop addon, I'm curious how I could port them over to blender if you have any ideas about that

It just occurred to me that your forum account is 2 and a half years older than your steam account. Idk why I'm intrigued by that, but I have this notion that steam accounts are the origin point for every PC gamer, so having a forum account before steam makes be like: "woah..."

My models (and Gmod ports) are available for use as long as i'm properly credited for making/porting it

Hey, I'd like to discuss about the permissions of use for one of your models.

I'm not interested in trading anything, sorry
