Modder Support

should the changes apply only to the listed ores, or do you want a more comprehensive overhaul of resource progression?

The information provided isn’t quite enough to pinpoint the issue. It would be helpful to know more about your setup. For instance, what screen recording software are you using, and is it set to capture the game window, full screen, or your entire desktop?

I had the same issue, so I ended up registering through gmail

I am trying to make an attack animation works for this entity, I have followed tutorials on youtube, looked into Geckolib's documentation but I can't find why it isn't working.
