Using the official level editor, i followed the level editor guide on rw modding wiki, I got a main map, the tilemap, the render png, settings(Copied from another map), Arena which is completely empty, and thumb which is a copy of the render png
So there are 5 files,
2 are pngs
3 are txts
I did not use the environment or size tab
when i try to open it in sandbox, it just... slowly turns white and doesnt turn back to normal like with most maps, i think its also low fps since the dev console takes a few seconds to open but doesnt lag when open, due to time freezing
