The color for detail objects are set in the detail settings using the 'Healthy' and 'Dry' colors. If you set both the 'Healthy' and 'Dry' colors to white then the original color of the material is used.
Nature Renderer uses a different coloring method than Unity's terrain system, so you have to tweak your color settings:
- If you use any of Nature Renderer's shaders then a Hue/Saturation/Value color correction is used. This will match the color of the terrain details to match exactly with the color set in the Healthy/Dry settings. For example, if you want your grass to be green, then you have to choose geen as the Healthy/Dry colors. In general, your colors should be darker and more saturated than the colors that you would pick for Unity's terrain.
The following example shows the colors used for Nature Renderer (top) compared to Unity's colors (bottom). If you leave the color values at the same colors that you used for Unity's terrain system then your grass will render with a very bright color (as seen on the bottom).
- If you use the Standard Shader or any other shader, then Nature Renderer will use the same coloring method as Unity's default terrain.
