How to Fix Visibility Issues with the XRay Texture Pack
Brightening Your Underground View
Sometimes, when you look through blocks using the resource pack, you might find that everything appears completely dark, preventing you from spotting any ores at all. Fortunately, there are a few simple methods you can use to illuminate your surroundings and make the transparent areas clearly visible.
First, you can brew some simple night vision potions and consume them to brighten up your field of view. Alternatively, if you have access to game commands, you can instantly give yourself night vision by typing /effect @s night_vision 999 2 true into your chat window. Another great option is using a Fullbright module or pack alongside your resource pack to eliminate shadows entirely and ensure every cave and underground cavern is fully lit up without needing torches.
