Some trunk scans done a LONG time ago. These were some of my first scans, and I was also able to scan pieces of bark, leaves and other things using a multi-angle approach in Substance Designer with controlled lighting. Maybe I will post the entire trees later on.
Something that was challenging about this one is the reflectiveness of the trunk. They tend to have very smooth surfaces sometimes which reflect a lot of the skylight. Though I think a polarizing filter can be used in such cases, I did not have one at this time.
