使用OSM数据构建城市资产City Building with OSM Data
City Building with OSM Data _ Introduction
Learn how to create a city block using data acquired from Open Street Map [OSM]. This information will be processed using three tools from SideFX Labs combined into a Houdini Digital Asset that can be loaded into UE4 using the Houdini Engine plug-in. The asset will procedurally generate points that can be used to instance geometry that is part of your UE4 project. These point use attributes to add variation to the look of the buildings based on information from the OSM data.

了解如何使用从开放街道地图[OSM]获取的数据创建城市街区。将使用SideFX Labs的三个工具处理此信息，这些工具将合并到Houdini数字资产中，可以使用Houdini Engine插件将其加载到UE4中。该资源将按程序生成点，这些点可用于实例化属于UE4项目一部分的几何。这些点使用属性根据OSM数据中的信息为建筑物的外观添加变化。

City Building with OSM Data _ Part 1 _ Prepare Open Street Map Data
The first step is to acquire the OSM data from the website. This can be downloaded in a format that works with the OSM tools in SideFX Labs. You will learn which information is available and how to trim it down to only the geometry that you need to create your city.

City Building with OSM Data _ Part 2 _ Generate the Buildings
To flesh out the city blocks into detailed meshes, you will use the Building Generator tool in SideFX Labs. This tool allows you to use outside geometry to add details by exporting points with attributes for instanced geometry inside UE4. You will wrap up the nodes into a Digital Asset to use with the Houdini Engine plug-in for UE4 to allow you to test it as new features are added to the system.

要将城市街区充实为详细的网格，您将使用SideFX Labs中的Building Generator工具。该工具允许您使用外部几何图形通过导出带有UE4内部实例几何图形属性的点来添加细节。您将把这些节点包装到Digital Asset中，以与UE4的Houdini Engine插件一起使用，以便在向系统中添加新功能时对其进行测试。

City Building with OSM Data _ Part 3 _ Create Road System
Starting with the data from the OSM file, the new SideFX Labs Road Generator tool will be used to build up the road system. You will learn how to set up width as an attribute and how to create the geometry in-between the roads. You will set up proper UVs for these areas and set up the roads for instancing in UE4.

City Building with OSM Data _ Part 4 _ Adding Props and Details
The next step is to add props such as posts, trees and garbage pails. You will learn how to set these up to work procedurally with the road system and how to add randomness into the size and location of the pieces. This approach could be easily repeated to add even more detail to this game environment down the line.

下一步是添加道具，例如柱子，树木和垃圾桶。您将学习如何设置这些程序以使其与道路系统正常配合工作，以及如何在零件的尺寸和位置中增加随机性。可以很容易地重复使用这种方法，从而为该游戏环境添加更多细节。
