Spacebuild News

SBEP is on the workshop, check below for the link!
The new Spacebuild is getting close to dev testing!

What is Spacebuild?

Build spaceships and land on distant worlds, perhaps building settlements or space stations. It comes with one demo map which you can download from the github repository which includes all of the near-solar terrestrial planets: Mercury, Venus, Earth(and Moon), Mars(and moons.) Gravity only applies when standing on a planet, and the Moon has less than half normal gravity. Mercury is so close to the sun that you will receive burning damage if you do not find shade quickly. It is difficult to build due to the planet's instability causing frequent tremors. Venus has such a heavy atmosphere that you will be instantly crushed if you venture onto the surface without a Life Support System(Air Exchanger) to stabilize your atmospheric pressure. Both Earth and Mars have regular day and night cycles, though Earth's atmosphere is so thick that you cannot see anything in space during the daytime, while on Mars you can faintly see the outline of objects and other planets in the ruddy daytime atmospheric haze.

How To Use

Spacebuild 3 is not like a normal gamemode, once you subscribe to it and start up a spacebuild map (any map with "sb_" in it's name) it will load, Here is sb_gooniverse, one of spacebuilds more memorable maps.

how to rotate doors?
Famous5000 Apr 17 @ 6:06pm 
So I found the solution. Load *literally* any SB map, and then it will work.

There doesn't appear to be any way to spawn generators, each time I try I get the error "caf_tool_disabled", and I can't figure out how to enable it...
Kupie Mar 16 @ 2:16pm 
Any recommended addons for things taking damage these days? Just noticed the fusion generators don't blow up (just trying in single player) like I remember them from 10+ years ago
