虚幻插件Landscaping & Landscaping Mapbox

Landscaping offers an easy way to import GIS data as single Landscape or World Composition (UE4) or World Partition (UE5) or Procedural/Static Mesh.
提供了一种非常简单的方式来导入GIS数据，可以生成Landscape、静态网格体及程序化网格，支持导入shp数据等等，同时使用了Georeference插件，很好支持了常见的地理坐标。

• 支持程序化生成道路；
• 支持根据土地利用（landuse）shp数据生成地表植被；
• 支持Mapbox在线地图纹理贴图；
• 支持地形Landscape变形使得植被和道路贴合。
