[No download links. This is a demonstration of something you can make with PAC.]
Changes since this video:
Better eye trails
Improved gun particles
Random Red effect while shooting was changed around and fixed
Spine (Can't see in video, but it was kind of off) was improved
A little something me and a friend made in a day and a half with PAC3 (Player Appearance Customizer 3), an addon made by CapsAdmin for Garry's Mod.
Model was cut up by limbs and parts in a modeling program and exported to OBJ's by Bizzclaw, he then uploaded the OBJ models and textures to a dropbox, and assembled the parts properly in PAC. This included a lot of messing with bones. It didn't end up perfect with many animations, but it's not too far off.
I then obtained the PAC, I spent awhile ripping the sound files for these guys from the Crysis 2 Files. Took me a couple hours to find something that would convert them. Uploaded them to dropbox, added lighting effects, sound effects, overheating effects, and gun effects. I tweaked a couple things to make it work better with the animations I used.
This is the result.
