This product consists of Shader Nodes for the Blender Shader Editor that allows you to mix multiple detail normal maps to a existing base normal map. This allows you to shade your models with high detail and realism without the need to use UDIMs or super high res textures. As it works with normal maps, it also means that you will not gonna need to use a fine displacement with a super high high resolution model to achieve a higher surface detail. The shader nodes also let you use the alpha channel of the normal map to control the roughness, metalness, specular and sub surface scattering.

This product also comes with 35 detail normal maps with a  matching grunge alpha that allows you to use the given shader nodes to modify the roughness and the other described channels.
