We need new artists it appears, I'm traveling a lot because of work, but I will try to get on and make a a list of what's needed for New textures, and some updated textures. I'm a bad artist so there's not much I can do but update the classic and transparent GUIs and the pack zips. Hopefully we can get some more people who would be willing to contribute to the pack.
So I have created an updated list of missing textures for 1.12/1.13. I cant update the OP at this time because the account it is made with, I cant currently access, but hopefully, il be able to fix that soon. I'm going to work on updating the Classic/transparent UIs for 1.12/1.13.
I'm super excited to hear the pack might be getting updated to 1.12/1.13! I used it years ago and recently jumped back into MC and no other pack compares... Really hope to see this pack keep continuing on!
Sadly alot of the artists that have been updating this pack are no longer around. If we can find more community members again to continue updating this pack then sure.
Anybody is welcome to add textures and try to fill in the blanks we have, whether or not they will be accepted will be seen....I've been doing some small changes to the mod support items I've been working on, but very rarely have free time to work on textures anymore sadly.
I will add what I can when I can, but don't expect much to come from me alone.
