Using Red Hitboxes Alongside Sodium, Lithium and Iris

The pack works through vanilla core shaders and does not need any other mod. It also works alongside common optimization mods like Sodium, Lithium and Iris, so you can keep your usual setup.

Setting Up With Other Mods

1. Launch your modded profile as usual with Sodium, Lithium and/or Iris installed.

2. Go to Options > Resource Packs and move Red Hitbox Resource Pack into the Selected column.

3. If you use other resource packs, place this one near the top of the Selected list. Packs higher in the list take priority.

4. Click Done, join a world and press F3 + B to confirm that the outlines are red.

If the Hitboxes Look Wrong

• The lines show the default colors instead of red, orange and crimson. Make sure the pack is in the Selected column. Then move it above any other pack that also changes shaders or debug visuals. Press F3 + T to reload resources without restarting.
• No lines appear at all. Hitboxes are off. Press F3 + B to turn them on.
• Block outlines look different. This pack intentionally leaves the black block selection outline alone. If that outline has changed, another resource pack or mod is changing it. Disable your other packs one at a time to find which one.
• You are using an Iris shaderpack. Toggle the shaderpack off in Iris's shader settings and check the hitboxes again. If the red lines return, the shaderpack is changing how the outlines are drawn.
