Houdini Foundations – Terrain 1 _ Shape the Terrain using Heightfields

Lessons: sidefx.com/tutorials/foundations-terrain/
To create terrains in Houdini, you will work with heightfields. You will start with a blank heightfield then add some noise and distortion to define the basic look of the landscape. As you work, you can tweak parameter values on the nodes while layering in details.

要在 Houdini 中创建地形，您将使用高度场。您将从一个空白的高度场开始，然后添加一些噪声和失真来定义景观的基本外观。在您工作时，您可以在细节分层的同时调整节点上的参数值。

Houdini Foundations – Terrain 2 _ Add and Visualize Mask Layers

Lessons: sidefx.com/tutorials/foundations-terrain/
You can set up layers on your terrain by first populating the mask then copying that information to a particular layer. You can do this more than once to add more layers. These layers can be used later to visualize key aspects of the terrain.

您可以通过首先填充遮罩然后将该信息复制到特定图层来在您的地形上设置图层。您可以多次执行此操作以添加更多图层。稍后可以使用这些层来可视化地形的关键方面。

Houdini Foundations – Terrain 3 _ Remap and Erode the Terrain

Lessons: sidefx.com/tutorials/foundations-terrain/
Right now some of the heightmap is below 0 and some is above. You are going to use a Remap node to change the range and then use the ramp on that node to add a ridge around the mountain. You will then erode the landscape to add new layers to the terrain.

现在一些高度图在 0 以下，一些在 0 以上。您将使用 Remap 节点更改范围，然后使用该节点上的斜坡在山周围添加山脊。然后，您将侵蚀景观以向地形添加新图层。

Houdini Foundations – Terrain 4 _ Scatter Points on the Terrain

Lessons: sidefx.com/tutorials/foundations-terrain/
To add trees and rocks, you will mask out the new plateau area then set up a special terrain scatter that will use this mask. These scattered points will then be used to copy instanced cones designed to represent trees. These will be replaced later in Unreal.

要添加树木和岩石，您将遮盖新的高原区域，然后设置将使用此遮罩的特殊地形散点图。然后，这些分散的点将用于复制实例化的圆锥体，这些圆锥体旨在代表树木。这些将稍后在 Unreal 中被替换。

Houdini Foundations – Terrain 5 _ Open the Terrain in Unreal

Lessons: sidefx.com/tutorials/foundations-terrain/
To bring the landscape into game engines such as Unreal Engine or Unity, start by creating a Houdini Digital Asset. Once you have the Houdini Engine plug-in set up properly, then this asset can be loaded into the game editor with the copied tree stand-ins importing as instanced objects. When you import the terrain into Unreal Engine, the heightfields will be recognized as a landscape. You can also import the asset into Unity using the Houdini Engine plug-in.

要将景观带入虚幻引擎或 Unity 等游戏引擎，首先要创建 Houdini 数字资产。一旦正确设置了 Houdini 引擎插件，就可以将此资产加载到游戏编辑器中，并将复制的树替身作为实例对象导入。当您将地形导入虚幻引擎时，高度场将被识别为景观。您还可以使用 Houdini Engine 插件将资产导入 Unity。
