Custom Slabs
experimental
easy
FORMAT & MIN ENGINE VERSION 1.21.40
This tutorial assumes a basic understanding of blocks. Check out the blocks guide before starting.
Introduction
Making custom slabs is a simple task, but if you find any drawbacks during recreating slabs, this tutorial will help you with it, and you'll be provided with a template for you to use.
Issues:
- Your custom slab will appear vertically centred when carried.
- Your custom slab may appear full-sized in item form (on the ground, in item frames, in hand)
Custom Slab
This will create a vanilla-like custom slab.
