Hi Proxyyt5, Let me help you with this. I’m sending you all you need to know to import a Gaea landscape to Unreal Engine 5.

Step by Step:

1. Create the Terrain in Gaea

  • Open Gaea and start a new project.
  • Set terrain size to 1009x1009 (best fit for UE5).
  • Add terrain nodes like Erosion, Mountain, Terrace to shape your terrain.
  • Go to Build > Export and save as 16-bit PNG or RAW (.r16).

2. Import the Heightmap into Unreal Engine 5

  • Open Unreal Engine 5 and create a new level.
  • Go to Landscape Mode (Shift + 2).
  • Click “Import from File”, select the Gaea heightmap.
  • Set X/Y scale = 500000 cm (500m), adjust Z scale as needed.
  • Click “Create” to generate the terrain.

3. Apply a Material & Collision

  • Assign a Landscape Material with textures.
  • Ensure Collision Preset = Block All in Landscape Settings.
