I use Gmod over SFM for posing because I find it to be marginally easier to use.All it requires is the right mods, and bam.
Now that we've got that out of the way, I was wondering, is it possible to get the model for the Balloonibouncer in Gmod? I wanted to use it for a poster but I can't seem to find any results on Google for it. It's probably just a model attached to the taunt itself instead of its own separate model, but it's worth a try.
