Every time that I try to load the world builder I keep getting an error and it tells me to go see steam support.
We’re gonna need some specifics. What error, exactly? Does steam support offer any solutions? What operating system are you using?
Also, you cannot run both the world builder and the main Boundless game via Steam at the same time.
You’ll need to run world builder directly from the game directory on your system (I’m on my phone at the mo so will see if I can, or someone else can, post up the directory later)
On windows 10
“C:\Program Files (x86)\Steam\steamapps\common\Boundless\worldbuilder\boundlessworldbuilder.exe”
Start a world in builder, click green dot at chunks to start your own world-server.
Start boundless from steam, select your world and you can jump around in your creation.
