For my animal test farm, I need to place grass of a different type than the standard.
I did not know if there was another possibility, so I just made a plugin for it!
Perhaps someone find it useful, too!
Extract switchgrasstype.zip in your RisingWorld/plugins-folder.
In game you can use the following chat commands:
/grass help list all command options
/grass def reset to default grass
/grass sav place savannah grass
/grass mdw place meadow grass
/grass tun place tundra grass
/grass ice place iced grass
It is also suitable for multiplayer.
