This is an update of the free 32x version of the Resource Pack from the future for Minecraft, with seamless 3D texture variations. It has better transitions and edges than the old update, and a few more blocks. To clarify this is a low resolution alpha version.
Use the CTMPOMFIX shader or patch to experience seamless 3D textures with variants.
Enjoy!
This is also available on curseforge here, and there may be preview images there.
