Breaking Changes

The following nodes may not be fully backward compatible with Gaea 2.1 or earlier builds.

  • Trees

  • Cellular3D

  • Debris

  • ThermalShaper (minor variance in results)

It is highly recommended that if you migrate an active project from Gaea 2.1 to 2.2, that you make a backup first and ensure all your nodes are behaving properly.

Gaea will attempt to create a Recovery copy in the Autosave folder for disaster recovery, but you should still keep a manual backup copy just in case.
