This is a blank canvas I made for forging outside of Tyrant. Enjoy! *ALL MAPS CAN BE DOWNLOADED FROM MY BOOKMARKS. My GT is Wally17.* Important Update: For whatever reason, in a custom game, it doesn't want you to spawn up there. Spawning outside of maps wasn't a problem until the Ghosts of Meridian update tweaked some things. However, Tyrant spawns you in only one location on the map so what I did is place a teleporter there and expand it's radius, so when you spawn you are immediately teleported to above Tyrant. You could place another teleporter in that spot on the main map and have each teleporter team based. So when you spawn, depending on if you are on Red or Blue team for example, you will go to your teams teleporter outside the map. You could do this with several teleporters so as the "spawns" would be somewhat random to prevent teleporter camping. Or you could just use FFA receiver nodes so it's as if the "spawns" are random. I will try to find a fix, but I've been at it for a while and so far that's the only thing I can get to work. If you figure out a fix, post it here. Update 2 (4/12/16): 343i must have done a minor update and not mentioned it. I went back into the canvas and put down some more spawns just testing some things again. I saved it and then killed myself. I respawned on one of the respawn points. So I then tried it in a custom game and I was no longer force spawned into the normal boundaries of Tyrant. As of now, things are back to normal, but 343i could break it again so I will still have the teleporter method employed on this canvas as a backup. Update 3: I made a more user-friendly version of the original canvas. In the original version, I mapped out all of the possible forging space, which is essentially broken down into 3 areas. You'll understand what I mean if you download it. I figured most people will want to only forge the top area anyway, so I made a very user-friendly canvas with a flooring already placed. This one is in my bookmarks as well and is titled "Out of Tyrant Canvas V2". Enjoy! Spoiler: Out of Tyrant V2 Images
I'm glad you guys like this! I have just finished updating the canvas because I really wanted it to be easy for people to forge on, and I wanted to showcase how big the forgeable area is. This was a bit of a tedious process, but it's pretty self explanitory how I've marked off where kill boundaries are. This update provides the maximum ceiling and floor area possible in this map.
You can definitely do more than 4v4 and I'm not sure what you mean about the physics budget, but you can't generate lighting on this map.
