NOTE to all whom it may concern (likely those configuring rftools dimensions.): rftoolsdim configs may not be exactly clear, to config rftools, you have to basically edit the individual saves config in minecraft/saves/worldname/serverconfig/rftoolsdim-server.toml this is exempt by dimlets, which can be modified by placing them in minecraft/config/rftoolsdim it is likely an empty folder at first, you need to drop your own custom configs in here to see some example configs, or to copy them over for small modifications, see the default files in the rftools source code at https://github.com/McJtyMods/RFToolsDimensions/tree/1.20/src/main/resources/data/rftoolsdim/dimletpackages - Packager of the Houngry I Pack.
