Hi:
Testing some new things, 2048 textures (1024 stock) and total new normal/bump maps, in goblin editor looks like this.
Note:
From my testings, I recommed low values for normal map, then paint the zones that you dont want to add "3d surface", for example most of the planar zones, with soft rounded brush with very low opacity and
#8080ff color (more paint = minor 3d surface).
Going to test new things.
Bye !!
