Unable to spawn instances. Ensure a large enough surface exists within the volume

I’ve imported a heightmap and getting this error every time I try to use the procedural foliage generator. Additionally I can’t even paint meshes on the terrain (The brush doesn’t appear when I mouse over the terrain)

I have tried:

  • Changing landscape collision settings
  • Made the spawner as big as the landscape
  • Starting a new project
  • changing all settings of both the spawner and the foliage

Ive seen other similar threads but no one has a working answer yet.
Please help

Does anyone know how to solve this??
