Thanks for this, I've merged your textures with the 1.6 Github Repo, and updated the Patcher, so most of them should be available through it.
Been using Leenhaart's latest with Unleashed with very few issues (Dartcraft would be nice) but Unleashed isn't an option on the launcher yet for it. Overlooked? Or still needs more work to be officially considered for Unleashed?
Tested the current patcher version you mentioned (picked the one for Ultimate) on Unleashed and it's stock, nearly. Only textures that appeared to be updated from a quick look were the chests, some armor and signs.
