I was experimenting with Blender's new Principled BSDF node. I came to know about various new maps - like Metalness map, roughness map and specular map.
Can anyone here please explain these maps in simple language here?
Previously I used to create Normal maps, bump maps, AO maps mostly in GIMP using Insane Bump plugins. It is very handy and fast.
But how to create these new maps? Do we have any similar plugins that will convert a texture into these new maps?
