This is an addon pack for the Minecraft pack Minecraft Reimagined but it can be played on it's own, but you will be losing a whole lot of the features.
This pack adds a bunch of more 3D and detailed models for the Minecraft Reimagined pack, which I personally felt was a bit either overmodelled or didn't fit vanilla enough in the "reimagined" vision I had. So I made an addon having the more detailed models in.
To install, simply have it over "Minecraft Reimagined" in the pack order in the resource pack menu, and it should be all good to go!
