这样我就在草坪中间创建了一个标准的平面图，在编辑多边形中选择边缘，开始挤压并调整地形，使其和草坪部分保持一致。

For that I created a normal plane in the middle of the grass part and in edit poly mode selecting the edges I began to extrude and adjust the terrain to fit with the grass parts.

为了使最后网孔呈现出更好的地形特征，我们创建了一个高度棋盘格式的平面图，使用scriptspot找到的Geometry Projection script将其投射到基础地形上。

In order to have a better topology of the final mesh we created a high-tessellated plane and we projected it onto the base terrain using the Geometry Projection script found on scriptspot.
