The white marble pack contains 3 marble textures in 1024x1024, 2048x2048 and 4096x4096 sizes, with PNG source files.
The black marble pack contains 3 marble textures (in the above sizes) complete with maps and source PNGs, as well as the 1024x1024 sized marble tiled (no source PNG).
The black and white packs were previously released, but I've done a bit of a reboot of them and changed the format of the the DDS files so they're a lot smaller than they were originally.
The blue, green and red marble packs contain 5 "solid" marble slabs and 5 marble tiles, complete with maps and source PNGs. These are a fixed size of 2048x2048.
The packs are loose files as there's no point in making archives.
In the interests of full disclosure the RGB packs were created with an AI program, with all rights reserved by myself, and released under a CC BY-NC-SA 4.0 licence. Please see the full permissions section for the licence terms and caveats.
Anyway love/hate/perform bizarre experiments on.
