Advanced Map Rendering Options
Caution
These options significantly change how the map is rendered. After changing a value it takes time for the change to appear, because every chunk has to be redrawn. Only adjust these if you know what you are doing; use the Reset button to return to the defaults.
This category fine-tunes the shading and lighting math the map renderer uses. The defaults are tuned to look good in most worlds.
Slope shading
These control the hillshading effect that gives the map its sense of elevation.
| Setting | Range (Default) | Description |
|---|---|---|
| shadingSlopeMin | 0 - 5 (0.2) | Lower bound for the slope shading range. Slopes below this are flattened. |
| shadingSlopeMax | 0 - 5 (1.7) | Upper bound for the slope shading range. Slopes above this are clamped. |
| shadingPrimaryDownslopeMultiplier | 0 - 5 (0.65) | How much downward-facing slopes are darkened (primary pass). |
| shadingPrimaryUpslopeMultiplier | 0 - 5 (1.20) | How much upward-facing slopes are brightened (primary pass). |
| shadingSecondaryDownslopeMultiplier | 0 - 5 (0.95) | Downslope darkening for the secondary shading pass. |
| shadingSecondaryUpslopeMultiplier | 0 - 5 (1.05) | Upslope brightening for the secondary shading pass. |
Light and brightness tweaks
| Setting | Range (Default) | Description |
|---|---|---|
| tweakMoonlightLevel | 0 - 5 (3.5) | The light level used as moonlight when rendering the night map. |
| tweakBrightenDaylightDiff | 0 - 5 (0.06) | How much the day map is brightened. |
| tweakBrightenLightsourceBlock | 0 - 5 (1.2) | How much light-emitting blocks are brightened on the map. |
| tweakMinimumDarkenNightWater | 0 - 5 (0.25) | The minimum amount water is darkened on the night map. |
| tweakWaterColorBlend | 0 - 5 (0.5) | How strongly water color is blended with the terrain below it. |
Ambient colors
These set the ambient tint applied to the map in each environment. Each
value is a hex color (#rrggbb).
| Setting | Default | Description |
|---|---|---|
| tweakSurfaceAmbientColor | #00001a | Ambient tint for the Overworld surface map. |
| tweakNetherAmbientColor | #330808 | Ambient tint for the Nether map. |
| tweakEndAmbientColor | #00001a | Ambient tint for the End map. |
