any idea what i'm doing wrong?
I added a Wooden Cauldron.
It has 12 levels and can only hold water.
Later it should also fill up when it rains.

But first, I have to solve 2 problems:

1. I can't fill it with water. if I do, an Vanilla Cauldron with Water appears.
2. I can not add it to the Creative-Menu / REI: it just adds an Vanilla cauldron additionaly.

I'm a C# software developer, and I've already modded something in Forge 1.12.2. Apparently I have to find my way around Fabric Modding first. Just wanted to say that I'm actually not a programming noob :)

Hmm, CauldronLib is really based around adding new fluids for the vanilla iron cauldron, not creating entirely new cauldron types. I suppose I could add extra functionality for that. Until then though, unfortunately CauldronLib won't really provide what you need.

ok thanks for the information.
