使用 Stamp Terrain 工具可在当前高度贴图之上标记画笔形状。在 Terrain Inspector 中,单击 Paint Terrain 图标,然后从下拉菜单中选择 Stamp Terrain。
如果一个纹理表示具有特定地质特征(例如山丘)的高度贴图,然后需要使用该纹理创建自定义画笔,则 Stamp Terrain 将会有用。
使用 Stamp Terrain 工具可以选择现有画笔并只需单击即可应用画笔。每次单击都会以所选画笔的形状将地形升高到设置的 Stamp Height。要将 Stamp Height 乘以一个百分比,请移动 Opacity 滑动条以更改其值。例如,__Stamp Height__ 为 200 且 Opacity 为 50% 时,每个标记的高度设置为 100。
Max <–> Add 滑动条可让您决定是选择最大高度,还是将标记的高度添加到地形的当前高度。
如果将 Max <–> Add 值设置为 0,然后在地形上做标记,则 Unity 会将标记的高度与标记区域的当前高度进行比较,并将最终高度设置为二者中较高的值。
如果将 Max <–> Add 值设置为 1,然后在地形上做标记,则 Unity 会将标记的高度与标记区域的当前高度相加,因此最终高度设置为两个值之和。
启用 Subtract 复选框,可从标记区域的现有高度中减去应用于地形的所有标记的高度。请注意,仅当 Max <–> Add 值大于零时,例如,将 Max <–> Add 值设置为 1 时,__Subtract__ 才有效。如果标记高度超过标记区域的当前高度,则系统会将高度调为零。
