If you're a patron over at Patreon you already have access to all of these textures.
What do you get?
This pack contains, like the tittle says, 100 different Sci-fi 4K textures with PBR maps, which include Color, Normal, Roughness, Displacement and Ambient Occlusion.
There's a Blender file with all the textures setup on the Asset Browser and you can just drag and drop the materials into the meshes. Bear in mind that you need proper UV unwrapped meshes for the textures to look good. You'll also need enough geometry in the meshes for the displacement to work.
A version with the SBSAR files is available. These files are opened with Substance Player and you can customize the textures and their resolution and generate new variations that you can then export to up to 8K. This allows you to create an infinite amount of texture variations.
