Pixelmon Mod

HEllo everyone.

IM new to pixelmon And I was wondering if you’re Pokémon can free roam?
So I can build sort of pastures where they can roam.

The closest thing to this that I'm aware of would be putting them into a Ranch Block, though that's probably pretty lame compared to what you're looking for. I don't think there's currently a proper way to do this, sadly.

I know for a fact that the custom NPCs mod lets you do this, however, it doesn't require you to catch said Pokemon you want to allow to roam free.

But without said mod, beats me. Probably not possible.
