It's a mod that shows your color when building, not just the standard green. So I play as pink for the most part. When a building is going up it will glow pink instead of green. you can see it on youtube right here. It seems google+ was using it. thanks guys
I was thinking it would be cool if the spray/nanolathe would be your main color or your complimentary color as well
I think this was something RCIX did a while back, he also messed with the math for the shader. *le look at video* Yup, that's RCIX's mod. It was one of the first shader mods done. If you look a bit further back, you'll notice that one of the devs states that teamcolor isn't passed from the game's data to the effects, so it's impossible to make the nanolathe spray a teamcolor.
