OK, in Booster's Lab you need to right click on the tile you want to change the type of in the tileset and then choose whatever type you want to choose with the left click.
Some types may lead to confusion, so my suggestion is to not be afraid to ask in the thread about that.
Well, I hope this is actually what you wanted to know and not something you already knew. That said, have a nice day.^^
i downloaded cave editor and when trying to edit tilesets there were tile types but i didnt know how to change it, but ill give it a try in BL
i know there's a reference somewhere that explains what each type does so i can use that
@Flake cave editor's ui is objectively better than BL's interface
BL may have more (useless) features, but CE gets the job done faster.
its up to personal preference to decide what to use
also in addition to what FortniteLover said, you might have to put your mod in a .zip folder and then extract it to prevent any damage done to your mod if you do use Cave Edtior
