This sticky launcher was re-animated using 3DS Max 2010. I used .eXe's demoman rig to help me do it.
I redid all the animations so the demoman holds it with two hands instead of one, similar to the third person view.
EDIT: Sorry I forgot to include the stickylauncher script file that includes team colour skins, redownload if you have already.
Also this will work with any other sticky launcher skin you have, except custom model sticky launchers (Not stickys).
Heres to the people who think his left arm is uncomfortable: his left arm is in a similar position to the third-person animations, I tried to make it look better but the reload animations didn't want to work. Sorry if you don't like it, its not even noticeable in the normal FOV anyway.
EDIT2: Turns out the .zip was corrupt, thanks to DerTeufel0707 on YouTube for pointing that out.
