This is the new updated Minecraft Tutorial on how to create and add 3D models for your resource pack. This works in all Minecraft versions from 1.8 onwards, but please do keep in mind, while the process maybe the same, there is a few things different about how it is done in each Minecraft version, whether the textures have a different name, or the json models have a different name. I did this video tutorial in Minecraft 1.12.2 and I pulled it straight from the same version I was doing the tutorial for. I recommend everyone do the same.

And please, do not pull models from someone else resource pack. Create your own for your own best work.

I will add a full description to this tutorial later on the week in this blog, until then, there is a video tutorial here!
