Frequently asked questions

Why can't I see the bright outlines on ores?
Make sure the resource pack is enabled in your resource pack menu and placed at the top of your pack list if you're using multiple packs. If you're still not seeing outlines, try moving to a new chunk or reloading your world.
Does this pack work with other resource packs?
Yes, but you need to place UHC Optimized at the very top of your resource pack list so its textures take priority over other packs.
Will this resource pack get me banned on servers?
Resource packs are client-side only and don't modify server files, so they're allowed on legitimate servers; however, always check your specific server's rules before using any visual enhancement pack.
How do I see players hiding underwater?
The pack makes water and lava completely transparent, so you can see any player or mob moving beneath the surface without obstruction.
Can I use this pack in regular survival mode?
Yes, the pack works in any game mode—it's designed for UHC but the clearer visuals and ore highlighting help in regular survival too.
Why is my world still dark even with this pack?
The pack keeps the world bright by adjusting lighting, but if caves are still dark, check that you've fully loaded the world and that your brightness setting in-game is set to maximum.
Does this pack change how my sword or armor looks?
Yes, it updates the glint effect on enchanted items and tweaks the shield position on your screen, plus adds new hit particles during combat for better visual feedback.
Will this pack affect my FPS?
Resource packs have minimal performance impact since they only change textures; you may see a very slight difference depending on your hardware, but it should be negligible.
How do I spot suspicious blocks faster?
The pack adds bright outlines to suspicious blocks just like it does for ores, making them stand out instantly from regular stone so you can loot quickly.
Can I customize which blocks get highlighted?
Resource packs apply all their changes as a package, so you cannot selectively disable individual highlights—you'd need to use a resource pack editor if you want to modify specific textures.
