The Endstar SDK allows you to use Unity to create custom props and terrain for use in Endstar.
After creating the terrain or props you can export them to the cloud and then use them in Endstar. You can even share them with others.
Unity 2022.3.28f1 is required, and you need to install the following modules: Android Build Support, iOS Build Support, Linux Build Support (Mono), Mac Build Support (Mono) and Windows Build Support (IL2PCC). Check out the Endstar SDK wiki page for full details on the installation process.
After exporting a prop to Endstar, you can use the in game tools to write custom Lua code to create new behaviors!
