Pixelmon Mod

Hello, i would like to ask if someone know what options or values of Pixelmon/Config i have to modify to avoid pokemons and NPCs spawn all around the world randomly, so i can make a server where the administrators create their own spawns, trainers and NPCs manually.

Thank you for your time.

You're able to override all spawn files via datapack. After the initial setup, you can copy over the defaults from the mod file (opened like a zip archive; path: "data/pixelmon/spawning/") under the same path in your datapack and edit/disable them to your liking.
A run-down of all spawn set elements can be found here: wiki/Better_Spawner/Spawn_Info

Thank you so much, thats what i was looking for a long time
