Starting again with some scan processing. This is a pretty basic and clean pavement surface, one of a few that'll be used in the patchwork-like make up of UK pavements.
Baked out and put through Substance B2M (Bitmap to Material) to get a roughness map. Hopefully getting a bit of reflectivity from the stones and adding a bit of variation to what is essentially a pretty bland texture.
The relief from the normal map is very slight, but fits with the kind of tarmac it is. There'll always be the opportunity to push it bit more later on, once I can see what it's like in engine, but I preferably want to keep this stuff as close to the scans as possible.
