Development Update #2 - Entity PBR

It's been a while since my last update here, but I finally have a few things to show! First of all, I've been revisiting some of the old textures that I never considered fully complete, giving them specific shapes and styles where there wasn't before. Take a look:

These are just a few of the changes I've made, but I have more exciting features in development as well! I discovered that in RTX the first pixel in the End Portal texture controls its uniform colour, while specifically the fifth pixel controls its uniform material. Through this I was able to give the portal a slightly emissive rough metallic surface with a dark bluish green colour, leading to a look that heavily improves upon the initial perfectly reflective and black surface that was present before. What do you think? (I have also made the End Frame eyes emit light now, which I believe improves them by quite a lot)

Finally, the biggest feature that I've been working on for Defined PBR's next update is adding PBR textures for all entities. I've been creating an addon that uses custom blocks to emulate the shape of the game's entities in order to allow me to preview what PBR textures would look like on them. Once the update is out, if Mojang finally adds PBR texturing support for Entities Defined PBR will already be fully compatible with the feature. Here are some of the textures I've designed:

Finally, here is the current changelog for the in development version of the pack I have so far, and is attached to this post. A lot of what's been implemented so far is all subject to change, so feel free to suggest a change if you do end up trying it out!
