- (Optional) Switch between Vanilla Experience and Performance Mode via the subpack slider
- Adjust individual toggles via the gear icon next to the pack.
Compatibility
Cesium only overrides a small, targeted set of files (particles, shield, fire, liquid, fog), so it's generally safe to use alongside other resource packs.
Possible conflicts if you use another pack that also modifies:
- Shield textures
- Fire/liquid textures
- Fog settings
If a conflict occurs, try adjusting the pack order in Resource Packs → Active Packs.
