Texturing in Unreal with Cesium

Overview: I am working on a project using Cesium Ion and the Cesium for Unreal plugin. I successfully imported a terrain as a Cesium 3D tileset but need assistance with texturing specific areas of the map.

Current Situation:

  • Terrain Import: Successfully imported terrain into Unreal Engine.
  • Desired Textures: I want to apply textures from Megascans to specific zones (e.g., roads, grass, rocks).

Challenges:

  1. Selecting Zones:
  • I’m unsure whether manually selecting zones is the best approach given the large size of the map.
  • Attempted using the brush tool but encountered issues since it’s not a landscape.
  1. Polygon Cartography:
  • Tried using Polygon Cartography but faced challenges with implementation.

Questions:

  1. What is the best way to select and apply textures to specific zones on a large map?
  2. Are there any recommended tools or methods for modifying default texture application in this context?
  3. Is there any documentation or resources available that explain how to effectively apply textures to Cesium 3D tilesets in Unreal?

Additional Notes:

  • I am new to this platform and appreciate any guidance or resources you can provide.
