Please note: The following instructions apply to Gaia, if you are using Gaia Pro, please follow this guide instead.
Gaia comes with a Scanner that allows you to create your own stamps. The scanner can be found in the "Advanced" Tab under "Handy Utilities".
The scanner can convert the following types of things into stamps:
- Grey scale images
- RAW files
- 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:
