Ok so i know some figured out that you had to keep the spawn points and objectives not the scenery on sandbox, but do you have to use every single one of the spawn points? Cuz i am making a small map and i don't think i could use all those spawn points.
Shouldn't be a problem. Use all the spawnpoints that you need, and when you're completely done with forging, delete any excess spawns.
By the way, at least from my own opinion I only think it's necessary to use the OLN canvas when I know for a fact that what I'm building is going to require a lot of objects. Or else I found it quite unnecessary to use when making a map.
Yeah that should be fine. Just make sure you don't interlock or anything after. What I would do is save a map with all 80 spawns as a new map just in case that you would make a second version so you can still interlock "safely" later on. For the first version, just "save as a new map" again.
Just block all of the remaining spawns with an object so they can't be spawned on, and you don't have to delete them in case you want to use them later.
But what if someone hacks and they spawn in the box o noes but just use what you need and the rest are extra you can choose to use them or not
