I have released my first sci-fi texture set on the Unity Asset Store.
This volume contains 26 materials, many materials are created with multiple combined textures like trims etc. that can be mapped separately.
All PBR textures are 2048×2048 in size and have Diffuse, Normalmap, Height, Roughness maps included. One material has an additional emission map.
