Is creative allowed for building contest

Quick question since it isn’t specified anywhere.

there are categories for modded /unmodded, but not how far the use of vanilla options goes.

Is creative/admin mode allowed for entries in the current building contest?

If yes, to what extent? There are huge differences between official server “survival” mode or creative SP with potentially drastically altered server settings e.g build anywhere, no stability loss. Is it just FFA or is unmodded considered to be true vanilla as per standard settings

You can build in Single Player (using creative mode as admin) and change the settings to whatever you want. As long as you don’t have any mods installed, it is considered unmodded.
