| alignToGround | Rotate detail axis parallel to the ground's normal direction, so that the detail is perpendicular to the ground. |
| density | Controls detail density for this detail prototype, relative to it's size. |
| dryColor | DetailPrototype 为“dry”时的颜色。 |
| healthyColor | DetailPrototype 为“healthy”时的颜色。 |
| holeEdgePadding | Controls how far away detail objects are from the edge of the hole area. |
| maxHeight | 草公告牌的最大高度（如果渲染模式为 GrassBillboard）。 |
| maxWidth | 草公告牌的最大宽度（如果渲染模式为 GrassBillboard）。 |
| minHeight | 草公告牌的最小高度（如果渲染模式为 GrassBillboard）。 |
| minWidth | 草公告牌的最小宽度（如果渲染模式为 GrassBillboard）。 |
| noiseSeed | Specifies the random seed value for detail object placement. |
| noiseSpread | Controls the spatial frequency of the noise pattern used to vary the scale and color of the detail objects. |
| positionJitter | Controls how Unity generates the detail positions. |
| prototype | DetailPrototype 使用的 GameObject。 |
| prototypeTexture | DetailPrototype 使用的纹理。 |
| renderMode | DetailPrototype 的渲染模式。 |
| targetCoverage | Controls the detail's target coverage. |
| useDensityScaling | Indicates the global density scale set in the terrain settings affects this detail prototype. |
| useInstancing | Indicates whether this detail prototype uses GPU Instancing for rendering. |
| usePrototypeMesh | Indicates whether this detail prototype uses the Mesh object from the GameObject specified by prototype. |
| Validate | Returns true if the detail prototype is valid and the Terrain can accept it. |
