Confirm the Minecraft version, loader, More Culling file, and dependencies all target the same environment. Remove duplicate jars and old versions left in the mods folder. The earliest dependency or mixin error in the log is often more useful than the last line.

Missing faces or flicker
Restore More Culling to defaults, then disable culling features one at a time. Test without shaders and custom resource packs. If the artifact disappears in a minimal setup, reintroduce visual mods one by one.
No visible performance gain
Use a repeatable benchmark in a geometry-heavy scene. If performance does not change, your bottleneck may be elsewhere. Compare GPU utilization, render distance, simulation load, shaders, and entity density.
How to report a bug
Use the upstream issue tracker linked by the project. Include the exact Minecraft version, loader version, More Culling version, dependency versions, minimal reproduction steps, logs, and screenshots or video when relevant.
Best-practice checklist
- Use the official distribution page or linked source repository.
- Match the exact Minecraft version and mod loader.
- Install only dependencies listed for that release.
- Test visual behavior before adding more optimization mods.
- Benchmark the same scene before and after changes.
- Back up important worlds before large profile updates.
