What I need now is a fluid that cannot be put into the world and cannot be bottled.
But after reloading, you can still pour it out with a bucket.
And I want to know how to make the fluid look like.
I referred to https://kubejs.com/wiki/tutorials/fluid-registry
StartupEvents.registry('fluid', e => {
event.create('thick_fluid')
.thinTexture(0xFF0000)
.bucketColor(0x00FFFF)
.displayName('Thin Fluid')
.noBucket()
.noBlock()
})```
