A set of seamless texture maps: BaseColor, Height, Normal, Roughness (PBR Metalic\Roughness), made by scanning from a sample size 300x200 mm. Settings for the tint of the main color can be made in the standard ColorCorrection node in the Material Editor. The material is as simple as possible, but with the possibility of flexible customization.
There is 1 panel in the scene (HxWxD): 1200 x 600 x 5 mm. It has flattening and the correct smoothing groups to apply a Displacement map to a material slot without breaking the edges of the geometry. The model has a multi-material, the back of the panel has a variant of the front material without Displacement to simplify rendering.
