Note: the use of OptiFine is highly recommended for this resource pack, though is not required.
When creating a 'vanilla edit' style of resource pack, its very important to keep Minecraft's distinct style and charm in mind. I feel a lot of packs fail to do this, or go for a more 'realistic' approach. Every change in this reosurce pack has reason behind it, from simply enhancing the visuals of the game, to making user interfaces more user-friendly, or even to adding lore to the Minecraft story. This resource pack changes Minecraft's assets for good reasons; not just for the sake of it.

To protect myself against any copyright issues, I want to mention that I am part of the Vanilla Tweaks team and I released some of the assets used in this pack onto the Vanilla Tweaks website. If you recognise a feature in this pack from Vanilla Tweaks, understand that it came from DefaultEx originally, and not the other way around (unless stated otherwise; see credits). https://vanillatweaks.net/about/
