guyystVTFEdit isn't gonna do me any good if I don't know what the file is. Just going through the TF2 vpks I got a ton of results when searching for stuff like 'train'. I can't really go through all of those.
? theres definitely a folder called materials/snowplow or something to help you narrow your search.
you really can go through all of those.
Well yeah there's a folder called that, but it's packed into the .bsp file. I can even open all the vtfs repsonsible for the health icons, but I can't change them inside the bsp.
I tried to open the map with VIDE to re-pack the materials with the icons made transparent, but VIDE won't even open cp_snowplow for some reason. (http://puu.sh/k9hJY/0f78afedef.png)
And yeah Benroads solution works for when you are currently playing on snowplow. But when watching a demo it sadly doesn't.
So yeah I'm still looking, starting to feel like this train icon was made to stay...
