Checking Resource Pack Conflicts
If you enable Lumen_NM Shaders and rivers, lakes, or oceans still look cloudy or oddly tinted, another pack may be overriding water visuals. Check your active packs with these steps:
1. Open Options > Resource Packs from the pause menu.
2. Check the Selected column on the right for any texture packs that alter water textures, sky colors, or biome colormaps.
3. Move those packs back to the Available column temporarily and click Done to reload.
4. Inspect a nearby body of water to confirm the Clean Water System's clearer coloration is now active.
Testing World Lighting in Daylight
Because Lumen_NM Shaders focuses on soft world-lighting adjustments and crisp daylight rather than heavy effects, checking it inside a cave or at midnight can make it seem inactive. Step outside into an open biome at midday—sleep through the night in Survival or run /time set day in a Creative test world. Toggle between Off and Lumen_NM Shaders in your Shader Packs menu to confirm that daytime contrast and bright world visibility are applying properly.
