Change Minecraft Blender Texture Pack?

Right now I'm trying to animate with Minecraft Rigs. However, I wanted to ask how I model objects at Blender (with the Minecraft blocks) and how to change the texture pack. Can I also set it so that the world looks like the Realistico Mod? (by Matteo Rizzo) So 3D us.w.

You would have to implement and model everything yourself.

You can make yourself an empty world there then with setblock insert all the blocks you need and then import this world into blender's videos on YouTube then separate them and then you have blocks that you can duplicate and do whatever you want
