The 2.8 beta crashes on me, also destroys files. Will have to wait for the final release. Not much tutorials on 2.8. The interlace and also eevee. It is like I have to relearn blender (sorta). So, in the meantime using 2.79. I might have found a solution in road asphalt. Not my best, or what ever, but it is a start. Will post a tutorial (images). Here. will look at link. ☺
