Focal Engine Mod FAQ
10 questions players actually ask, answered.
Do I need OptiFine to use this mod?
Yes, OptiFine must be installed first. Focal Engine Mod works as an extension to OptiFine's shader system, so both are required for the mod to function.
Why do my shaders look flat or wrong after installing?
Make sure you've enabled shaders in OptiFine's settings and selected a shader pack compatible with Focal Engine (like Continuum). Without an active shader pack, the mod won't apply its advanced graphics effects.
Can I use regular resource packs or do I need PBR packs?
Regular resource packs work fine, but PBR (physically-based rendering) resource packs are designed to take full advantage of Focal Engine's realistic materials and lighting. Non-PBR packs will still look better than vanilla, just not as detailed.
My game is running slowly with this mod. What should I do?
Check the performance guide in the wiki—try lowering shader quality settings, reducing render distance, or disabling intensive features like volumetric clouds and contact shadows. You can also adjust these in the in-game menu without restarting.
How do I download shader packs without closing the game?
Open the in-game menu (accessible from the mod's interface) and use the built-in shader/texture downloader. You can browse, install, and update packs directly without leaving Minecraft.
Why aren't my puddles and water ripples showing up?
Water effects require both the shader pack and resource pack to support them. Check that your shader pack is Focal Engine-compatible and that realistic weather is enabled in your shader settings.
Can I use this mod with other graphics mods like Sodium?
No, Focal Engine is designed to work specifically with OptiFine. Using it alongside other rendering mods like Sodium will cause conflicts and won't work properly.
Do I need to log into an account to use the mod?
The in-game menu includes an account login feature for downloading and managing shader/texture packs, but it's not required to use the mod's core graphics features.
Why are my light rays and shadows looking weird or glitchy?
This usually means your shader pack settings don't match your hardware capabilities. Check the troubleshooting guide for visual glitches, and try adjusting shadow quality or contact shadow intensity in the shader menu.
Will this mod work with my old GPU or low-end computer?
Focal Engine is demanding and works best on mid-range or better hardware. If you have an older GPU, you can still use it but will need to disable or lower advanced features like volumetric clouds and detailed lighting effects.
