never seen that before but that's p cool.
I learned what I know about huds from all kinds of sources, but I got started with flames guide. After reading it and referring to it countless times, I eventually learned the rest from trial and error.
But to op: you may have a hard time finding someone to help you with all that stuff. I recommend familiarizing yourself with the guides omni and I posted, and trying stuff out on your own. You'll absorb the knowledge much better this way, and you can always ask [less broad] questions as you go along. Either route you choose, it won't take you long to realize how complicated making and editing huds can be, at least until you've spent a good amount of time working with them. But imo, it's easier to teach yourself a lot of this stuff rather than listening to someone else try to teach you.
Good luck.
He's right go look at that link you'll find awesome things
