Knotty Tree Trunk #4 Photogrammetry image pack.
Some of the tree trunk shapes remind of a fairy-tale character, you can see animal eyes, mouth, teeth.
This data set allows you to build your own 3D scans or seamless PBR materials, using photogrammetry software. Reconstruction tested in Agisoft Photoscan. I recommend doing additional shadows\highlights corrections after baking albedo textures.
This image pack can be useful for texturing and for references.
