EXTREME GORE WARNING!
An SFM recreation of that JayDaddy video with the audio by Alex the Doggo and a little something extra
The amount of custom models in this is insane. I ported all Postal 4 assets seen, even The Dude, as the current version is different than the Gmod model. This has been done with the personal blessing of Running With Scissors.
Some easter eggs:





This is what I consider my Magnum Opus currently because I feel proud for managing to make the trash bag move like a trash bag does, especially when Art is trying to rip out of it. This was done purely through experimentation and guesswork using flexes and custom bones on the Left 4 Dead trash bag model, and I am extremely happy that it turned out as something very comfortable and easy (for the most part) to animate with no issues in the final product. Art ACTUALLY rips out of the bag, the bag shakes around like he's inside of it, and the hole actually expands as he rips out.
Also, despite all of that, the hardest part to animate was "Gucky"

Not because of the mask, or the rig of the model, but because of how precise the movement had to be to look convincing. I spent two weeks on it alone out of the 30 days I spent animating this. The perk of being an autistic unemployed fuck (thanks for the genes, mom!) (no, seriously. Diagnosed in 2005, baby!) is that you have all day to do nothing but animate. I even kept experimenting with re-rigging the bones on the coat to make them move more realistically, but it didn't turn out how I wanted.

Notice how GUCKY is in an awkward pose. I wanted him on a better pose, but the rotation looked very unsmooth when I did so and this segways into the next frame better. Also notice the coat's strange dome-like shape. I couldn't figure out how to fix it. Hopefully Postal 4 one day adds physics itself and re-optimizes the model to have it. The model "supports" it "for a future update" that was teased years ago - this pretty much means that its legs and the coat are separate. However, the shirt and coat are fused, so I can't get it as loose as I want, so I've decided to add a belt to future edits, although my last belt edit is totally gone due to a hard drive crash on my secondary workstation.

Dude has re-kindled his inner child and loves playing with toys again.
The lore I came up with is that Chucky's spirit was transferred into a mask of his own face, and then Chucky put it on and Gary took over his body. Gary can only rest when he kills his killer. Being that this is Postal, the timeline diverges from ours, but nobody in Postal stays dead, either due to psychosis or something from the local military bases, maybe even both. I just know that it smells like shoe polish all the time in this fucking shithole of a city.

SO LONG AND GOODNIGHT!

I'd also like to thank my Autism for making my special interest Postal instead of something cool like trains, computers (it is one, but not THE one), or Hulk: Ultimate Destruction for the Playstation 2.
