How do I create a liquid with a custon texture and a bucket for it? please help!!!

It's only possible with variables. I'm not too good with that stuff, but from what I recall somebody else also asked this question, and someone said that you can try to make it so that if somebody right-clicks with a bucket, a custom bucket-item will be placed into their inventory, and vice-versa.

I cannot confirm this.

I am not possitive if the game adds a color formula to liqids in order to change the color. If i am right mcreator saves the texture of the fulid that you make somewhere in the mods files. If this is true you could make a new liqid texture to replace the old one, thus creating a custom liqid texture.

I am not sure that what i am saying is true so i will test it and then walk you through the steps
