by kcxr

Kacper Utils is a client-side Fabric mod that bundles visual PvP tweaks, all adjustable from one in-game settings panel.

What it does

Kacper Utils groups several small visual and sound changes into a single client mod. Its features cover combat feedback such as a custom hit sound, a damage tilt effect whose intensity can be set or turned off, and a Kill Effect sound that plays when the player gets a kill. It also recolors totem, critical hit and enchantment particles, and can load custom PNG textures for them. Players can switch on a Keystrokes overlay that shows WASD and mouse input, and adjust the golden apple eating animation.

The rest of the mod is about the look of the world and the interface. World Tweaks sets a custom fog and optional ambient fireflies, which can be limited to the third-person F5 view. Misc Tweaks offers fullbright, hidden potion icons, a hidden elytra, low fire and a hidden totem. Pop item and server resource pack skipping are also available. Open source is not offered: the code is released under the MIT License. The mod is published for Fabric only, for Minecraft 1.21.4, with version 2.0.2 as the latest file, dated 2026-07-24.

Only the player's own client needs Kacper Utils. Servers run without it and it changes nothing on the server side, so every setting is local and works on any server. Options open from a menu bound to Right Alt, which can be rebound.
