BTB Back to Basics Shaders FAQ
10 questions players actually ask, answered.
How do I enable BTB shaders after installing?
Open your Video Settings in-game, go to Shaders, and select BTB Back to Basics from the list. The shader will apply immediately to your world.
Why do my textures look blurry or stretched with this shader?
This is the intended PS1-style effect, but you can reduce it by adjusting the shader settings—lower the pixelation or polygon distortion values in the shader options menu to make textures sharper.
Can I use BTB shaders with my resource pack?
Yes, BTB shaders work with most resource packs, but simpler packs designed for vanilla Minecraft work best; highly detailed packs may clash with the retro aesthetic or cause performance issues.
My game is lagging with BTB shaders on. How do I fix it?
Lower your render distance, disable advanced lighting options in the shader settings, or reduce shadow quality—BTB is designed to be lightweight, so lag usually means other settings are too high for your hardware.
Do I need Optifine to use BTB Back to Basics Shaders?
Yes, BTB requires Optifine or a compatible shader loader like Iris to function; without it, the shader pack won't load.
Why do water and transparent blocks look weird?
The PS1 effect distorts transparency and reflections intentionally for the retro look; if it's too extreme, adjust the transparency or water settings in the shader configuration to find a balance you prefer.
Can I use BTB shaders in multiplayer?
Yes, shaders are client-side only, so they won't affect other players or require server changes—everyone sees their own shader effects.
What's the difference between the shader settings for performance vs. visuals?
Performance settings reduce shadow detail and lighting calculations to boost FPS, while visual settings increase effects like bloom and polygon distortion for a more pronounced retro look; adjust based on your hardware.
Why do mobs and entities look strange or glitchy?
The shader applies the PS1 effect to all entities, which can make them look distorted or low-poly; this is normal, but you can disable entity shading in the settings if it bothers you.
Does BTB work with Sodium or other performance mods?
BTB requires Optifine-compatible loaders and may conflict with Sodium; use Iris instead, which is designed to work with Sodium while supporting shader packs like BTB.
