Frequently asked questions
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.
