Hi! Welcome to the forum for Platinum Arts Sandbox Free 3D Game Maker. I currently have the forums locked as I am attempting to properly update them. If you have any questions please e-mail me through the Platinum Arts website.
Here is a tiny mushroom island I created using https://github.com/Hirato/lamiae, which is a game engine created by Hirato, who made the RPG mode for Platinum Arts Sandbox.
Also, is anyone still active here on the forums?
