Love the dimension. Only real issue I personally have with it is the activation via the Ancient City's portal - mostly because I have the Deeper and Darker mod installed. Although I quite like the idea of being able to travel to two different dimensions depending on what activator you use on the frame, I'd like to request a config option to set up a custom portal frame. Could this be possible?

Thank you in advance for your time and patience.

You can configure which blocks are accepted via data packs!

Oh fantastic, thank you!
I can't seem to make it work though, could I please have more help? A template folder could help!

Yeah sorry, unfortunately I can't seem to make it work?
This is how my datapack is setup - what am I doing wrong?

and in the specified json I have:
{
"replace": true,
"values": [
"minecraft:end_stone_bricks"
]
}

Nevermind I'm dumb! Forgot to close all of this in one folder.
Thank you!
