Gaia comes with a Scanner that allows you to create your own stamps.

The scanner can convert the following types of things into stamps:

  • Grey scale images
  • RAW files
  • Terrains
  • 3D models (as long as they have a collider on them)
  • World Machine w16 terrain export files

There is a great site called Terrain Party that allows you to get real world locations in the form of a high resolution .png image file which can then be imported into Gaia.

To learn how to import and convert these to stamps check out the following tutorial:
