For a project I was working on, I needed to place dead bodies on the ground, but neither dead Fixits or dead Ironsnouts made sense, so I began tweaking snoutx10k. Since I'm no modeller at all, and have no modelling skills whatsoever, a visor instead of the snout's face was the easiest thing to do, and so I did.
Eventually, I began using it as my snoutx10k player replacement, and tweaked the skin and config around to make it stand out more for each team's side (as I had some troubles myself with differentiating between red and blue players before with the original snoutx10k, which -as it turns out- is partly due to the 'morning' skybox used as a reflection map). I'm pretty satisfied with how things turned out.
Depicted on the picture is a comparison between visor and snoutx10k. Note that these don't have the 'brightening of player models' enabled, as they're all mapmodels. So in-game, if you have the brightening enabled, they stand out just a bit more... For those curious to what I changed: I tweaked the helmet, the torso (made it less fat), and the arms.
Also note that the download size is 17.9MB, and that this is more-or-less DELIBERATELY packaged wrong, as you might want to BACKUP YOUR EXISTING SNOUTX10K FOLDER in case you want to revert back to the original Snoutx10k.
