Tree Bark - Photogrammetry based Environment Texture

Scan I processed this time is an example of how to capture a non flat object's surface. I wanted to show the way I build lowpoly for non planar object and I picked a tree trunk as it seems to be good example.
Another big change: this time I decided to show my workflow preview as a short video. Fun part was to compose background music, hope it is fine :)
I also tried another trick - forced mesh density to hold more vertex color data for baking, but waiting for confirmation from Agisoft it makes sense.
I am still testing part when I combine baked height map with bent normal based one. Works very well but as I haven't tested it on really extreme and broken surface yet so I am still waiting before I update that section in my tutorial.

An experiment with Photoscan, with forced highpoly density to get better vertex color coverage. Not sure if suggested by photoscan maximum highpoly value is the one, dense cloud has enough info to cover. Visually looks better. Will see.
