Yes, use the "slate_font" convar.
set it to the name of a font currently installed on your computer.

are fonts changable?

is there anyway i can disable the text so only the health and armor rings show?

Excellent HUD! Really like the modern bars, in fact. Couple of issues to report, though.
slate_ammo_style 2 doesn't seem to be working for me. No ammo counter is visible regardless of weapon. slate_ammo_style 1 still works, though.
slate_ammo_reload 1 doesn't look like it's working for me, either. Even with Half-Life 2 weapons, I don't see the bar appear anywhere when reloading.
That's all I've noticed as far as bugs go, but if I could make one request, would you consider seeing if you could add support for DyaMetR's H.E.V Mk V Auxiliary Power? I prefer it to GMod's built-in HEV support due to the Episodic flashlight, and would like if this HUD had appropriate elements for the aux. power meter and flashlight meter.

so anti-aliasing affects the hud? that is interesting :o

Thanks for the feedback! I'll look into adding color and transparency options, as you said. However, the smoothing is something determined by your game's current anti-aliasing setting. (look into mat_antialias)

could you add some color or transparency options? maybe some smoothing on some parts so its less pixely? other than that this hud is amazing!

The ring hud reminds me of payday 2, very nice

airplanes in the night sky are like shooting star :))

wow this kinda reminds me of a hamburger bro...............

look man
