Red Hitbox Resource Pack FAQ
10 questions players actually ask, answered.
How do I actually see the red hitboxes?
Open Options > Resource Packs, move Red Hitbox Resource Pack into the Selected column, and click Done. Then press F3 and B together in game to show hitboxes. Press F3 and B again to hide them.
I enabled the pack but I don't see any red lines, what's wrong?
The pack only recolors the debug hitboxes, and those are hidden until you press F3 and B together. If you have pressed it and the lines still look like the standard colors, check that the pack is in the Selected list and sits above any other pack that changes shaders or debug visuals.
What is the orange line on mobs for?
The orange line marks the entity's eye level, or head height. It lets you see exactly where a mob or player is looking from, which helps in combat and when lining up shots or hits.
What does the dark red line sticking out of the hitbox mean?
That dark crimson line is the look vector. It points in the direction the entity is facing and shows its line of sight. It is the darker line, distinct from the bright red box outline.
Does this pack change the black outline when I look at blocks?
No. The normal black block selection outline is left untouched, so building and mining look exactly like vanilla. Only the F3 and B entity hitbox lines are recolored.
Do I need Fabric, Forge, OptiFine or any other mod for this to work?
No. It is a plain resource pack that uses the game's vanilla core shaders and has no extra mod dependencies. You just enable it in the Resource Packs menu.
Will it work with Sodium, Lithium or Iris installed?
Yes, the pack is made to work alongside optimization mods like Sodium, Lithium, and Iris. If the colors ever don't show, first check your resource pack order to make sure nothing else is overriding the hitbox visuals.
Can I use this on a multiplayer server?
Yes. It is a resource pack that runs on your client, so the server doesn't need it installed. Only you see the red lines, and other players see whatever their own game shows.
Does the red box change when someone sneaks, crawls or rides a mob?
Yes. The red outline follows the entity's real hitbox, so you can watch it adjust when a player sneaks or crawls. It also stays visible while a player is riding a mount, which makes it easy to compare poses.
Will this pack lower my FPS?
It only recolors the debug hitbox lines using vanilla core shaders, so it shouldn't cost noticeably more than vanilla hitboxes do. The lines only render while you have F3 and B toggled on.
