I've placed it here, as it's not only about photoshop. Is it possiple to somehow clean up a texture made by a 3d scanner from shadows, flares and other data exept colour. I'm trying to create a PBR texture, and it needs separate maps for diffuse(colour), roughness, metalness channels. For non organic models it was easier for me to just create new maps (In Substance Painter with some help of Photoshop). Bun now I'm trying to deal with this head, and I'm nor so good to repaint it properly.
