The Quixel tree trunks are interesting and you've displayed them nicely. They come in handy if you are using Speedtree as you can start the construction of a custom tree using the the scanned trunk and texture and then extend and modify the body of the tree upwards using the initial form and textures to complete your model, adding additional textures for branches if needed, not to mention leaves, needles, etc. BTW I sent you a PM.
