### 一.新建地形 ###

在模式中点击山形状的图标会出现以下界面；

下面那几个你可以自己随便调节一下看看都是干什么，都是可视化的东西，很简单

![20200229113337802.png][]

至于这个材质球，在你创建项目的时候如果是默认的，那么系统会默认给你添加新手包

找到StartContent这个文件，点击进去

![20200229113451590.png][]

选择倒数第五个Materials，里面有很多材质，拖拽到地形即可

![20200229113534339.png][]

一切完成后点击创建

![20200229113655104.png][]

点击管理，选择工具最后一个“编辑样条”，

在地形上按住Ctrl，点击鼠标左键，创建样条

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 1][] ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 2][]

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 3][] ![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 4][]

创建完之后在左侧选择分段，全选样条（或者点击其中一条样条 Ctrl+A全选）

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 5][]

左侧找到Landscape Spline Meshes，点击加号，展开0

会出现如下：  
网格体蓝色框中是可以选择的地形样式

材质绿色框中是创建地形的材质

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 6][]、

举例：创建鹅卵石道路

选择正方体，鹅卵石材质，高度为0.02

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 7][]

效果：

点击小山可以调节样条 [https://blog.csdn.net/alzzw/article/details/104570101][https_blog.csdn.net_alzzw_article_details_104570101]

其他：

Q：因为我们的地形很平所以看起来很自然，那么如果是山丘怎么办?道路下面不就有中空或者在地形下面？例如这样

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 10][]

A：在管理，编辑样条工具下有一个：将地形变形为样条，点击所有样条

![watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2Fsenp3_size_16_color_FFFFFF_t_70 11][]

地形就会自动填充样条（秒啊）
