If your world still looks like plain vanilla Minecraft after selecting N87 Legacy Warm Shaders, or if water, skies, and block shadows appear broken on your legacy setup, a quick check of your loader and resource pack order usually resolves the issue.
Checking Loader and Pack Conflicts
1. Open Options > Video Settings and confirm a Shaders button is present; without an active shader loader like OptiFine or Iris, the game cannot read shader packs.
2. Open Options > Resource Packs and temporarily move custom texture packs to the inactive column. Because N87 Legacy Warm Shaders is built to keep the classic blocky look clear, testing with default textures helps isolate whether a resource pack is overriding sky or water visuals.
3. Inside the Shaders menu, make sure any built-in internal shader option is deselected and N87 Legacy Warm Shaders is highlighted.
Resetting Shader Settings
1. Go to Options > Video Settings > Shaders and open the pack's settings screen.
2. Click the Reset button (if provided by your loader) to restore the default warm sunlight and soft shadow behavior.
3. Press F3 + R or re-select the shader pack in the menu to force a clean reload of lighting across the terrain.
