Stratum is a realistic, high resolution and high quality resourcepack, built with shader compatibility in mind. It supports many of high end shader effects, including Parallax Occlusion Mapping, which provides a new layer of depth to surfaces in game, as well as high quality normal and specular maps. Stratum also uses fully Physically Based materials, just like many AAA titles do today.
Stratum is specifically built with Continuum in mind, but it should work well with a variety of other Minecraft shaders. It should also run on a variety of systems; more modest gaming rigs can choose one of the lower resolution options, such as 256x, or maybe 512x. Higher end systems can go with 1024x, and the highest end systems of the future can use the full 2048x pack (In it’s final form OptiFine will not be able to load this pack on modern hardware, upon novas completion this should become a more viable resolution for a wide range of systems).
For now, the pack is only going to cover the base Minecraft textures, but in the future there will likely be add-on modules for mods, such as Better Foliage, or even Buildcraft. That said, as it is still currently being developed, the focus is only on finishing the base game textures for now.
If you would like to try Stratum now, or just support the project early, you can purchase a Early Access package below. There will be regular updates to the pack as it is developed, and they will be pushed to the GitLab for all Early Access users to try.
