【Painting Grass 画草】Painting grass works the same as painting textures or trees. Select the grass you want to paint, and paint right onto the Terrain in the Scene View画草跟画贴图和画树是一样的。选择你想要的草去画，那么画的将反应在场景视图上面。
Painting grass is easy as pie 画草是易如反掌Note:When you have a ***sh selected, move your mouse over the Terrain in the Scene View and press F. This will center the Scene View over the mouse pointer position and automatically zoom in to the ***sh Size distance. This is the quickest & easiest way to navigate around your Terrain while creating it.注意：当你选一个刷子后，在地形上移动你的鼠标，按F。它将使场景视图定位在鼠标指针中心位置，随距离自动缩放刷子大小。这是一种最快最简洁的导航方法。
【Editing Grass 编辑草】To change any import parameters for a particular Grass Texture, select it choose Edit Details button->Edit. You can also double-click it. You will then see the Edit Grass dialog appear, and be able to adjust the parameters described above.要想更改特定草贴图的导入属性，选择Edit Details button->Edit，你也可以双击它，然后在上面调节参数。You'll find that changing a few parameters can make a world of difference. Even changing the Max/Min Width and Height parameters can vastly change the way the grass looks, even with the same number of grass objects painted on the Terrain.你将找到一些参数去改变它。改变最大最小宽度和高度参数可以改变草的样子，即使草的数量一样。

The same number of painted grass objects, now wider and taller
