i wanna make a map where the sandbox crypt floor is covered in shield doors but u can only have like 8... i was wondering which map would be the best to create this or if there was a way to break the run time maximum...
There's no way to get more than what you have. You'll just have to make do with the 8 you have. As Dow said, it might be possible with mods, but they aren't allowed on this site. I recommend trying to do whatever you're trying on foundry... because you have large and small shield doors, so you'll have more to work with. But you'll need to save/quit for every piece to make it into flooring, because they'll flip upside down when you try to make flat flooring out of them on foundry. How many large/small shield doors do you have on foundry anyways?
... It's just so you can get the shield doors to stay flat. You could ghost merge I suppose to get rid of the ugly thing that holds the shield door.
