Frequently asked questions

Do I need to install anything else to use this resource pack?
No, the pack works as a standalone resource pack in your resource packs folder. However, it pairs best with a shader pack to display the moody shadows and mineral illumination the textures are designed for—shaders are optional but recommended.
Will this pack change how the Nether or End look?
No, this pack focuses exclusively on underground biomes and deep caverns. The Nether and End remain unchanged, so you can use other resource packs for those dimensions if you want.
Can I still see ores clearly when mining in dark caves?
Yes, ore blocks are designed to remain clearly visible and distinct even in dark tunnels, so you won't struggle to spot what you're mining for.
Does this pack work with the Pale Garden biome?
Yes, the pack includes textures for the Pale Garden biome in newer game releases, so it integrates with current Minecraft versions.
What texture resolution is this pack?
The pack uses 64x resolution blocks based on real photographs, which provides detailed realism without requiring extreme performance overhead.
Will my FPS drop significantly when using this pack?
At 64x resolution, performance impact is minimal on most systems, especially compared to higher-resolution packs. Pairing it with a shader pack will have more impact on FPS than the textures alone.
Does this pack change mob textures?
No, the pack focuses on block textures for underground environments. Mobs remain unchanged unless you use a separate mob texture pack.
Can I use this pack with other resource packs?
Yes, you can layer this pack with others in your resource packs folder—just ensure Mostly True Beneath is positioned above other packs in the list if you want its textures to take priority for underground blocks.
Does this pack affect structures like Strongholds, Trial Chambers, and Ancient Cities?
Yes, the pack reworks textures for these underground structures, giving them more realistic stone brick, moss, and architectural details while maintaining readability.
What should I do if the caves look too dark to see the texture details?
Add more lighting to your underground base or caves using torches, lanterns, and other light sources—the detailed textures are designed to shine with proper illumination, and a shader pack will enhance shadows and highlights further.
