I'll be making a couple episodes about VTF crosshairs. Episodes will be made spontaneously and on no set schedule. Though I promise to not wait 2 years (this time)
Episode 1 is up. It explains the layout of the folders and how VTF crosshairs work in the first place.
Later episodes will delve into editing the folders (changes to scripts, changes to vmts, reloading VTFs whilst in-game, etc). And some episodes on my methods for making crosshairs and demonstrations.
