1) Extract/Unzip the hud and copy the OMP Hud folder
2) Paste The folder to your custom tf folder (C:\Program Files (x86)\Steam\SteamApps\common\Team Fortress 2\tf\custom)
NOTES:
I suggest using "tf_hud_target_id_disable_floating_health" "1" since the floating version is not as consistan and can have problems.
The original rgb code for the damage numbers is: hud_combattext_red 255; hud_combattext_green 255; hud_combattext_blue 30
All the hud crosshairs can be found inside the scripts/crosshairs folder!
It is possible to enable them from the crosshairs.res file by setting "visible" "1" for the wanted crosshair.
It is also possible to easily animate them so the crosshair turns red on damage by editing the HudAnimations_Crosshairs file, you can find all the instructions inside the file!
