Very new to arnold and nodes. I am trying to make a material where there is stone with egyptian hierglyphs engraved into the stone.I do not know how to make sandstone or limestone from scratch and I do not know how to add the glyphs on top afterward. Is there layering involved? displacement? I am not sure where to start. There aren't a lot of sources online about this specific thing. Any tips would be very helpful. Here is a reference and here is the image that I was going to use as a part of a pbr material. Thanks!
