I spotted some interesting dried bark today and shot a 1min video at 4k/60fps on my phone of the surface. I pulled out every 15th frame and ran it through Reality Capture to see what would fall out. Some cleanup in Alchemist and Artomatix led to these results. I think there is more potential here but I didn't have time today, one to return to!
