Hello people, it has been a long time. By sheer luck I went back to the thread today and realized someone was working on connected textures.
I am the one who did the Sandstone CTMs that you've been talking about, as well as the Lapis one (which is actually supposed to be the top of the block texture, the side one being different, I'm also not sure it was supposed to be in the stack in the first place).
Apparently the regular Sandstone one was missing from the stash. I did them for my own project back then (which explain the weird color) but they ended up gathering dust in my hard drive, so nice to see they could serve a purpose. If people are interested by them for the main pack then here they all are:
And here is a link to the individually cut Sandstone textures pictured above, in the old MCPatcher format: http://www.mediafire.com/file/qz0owwwmy3ouxqo/Sandstone Block by Archibald TK.zip
Within the spoiler is a red version (and a random picture), but you'll have to cut it manually.
It's only for Dokucraft thought, please do not use them in your own personal pack!
Tell me if you need me to upload all of them as individually cut 32x textures.
