Oak Tree Bark - Photogrammetry based Environment Material
And another oak tree bark I initially captured 5 or 6 years ago and just reprocessed with my current workflow to turn it into a decent bark material I can apply to trees. Since I find it extremely useful for outdoor scene vegetation , I added it to my materials library:

as 'gb_BarkOak612'
While it looks ok-ish if used alone, I expect it too look much better when blended together with the previous one. I plan to share the final result soon in form of another post.. end even considering to turn it into some quick video tutorial showing importance of such materials when it comes to vegetation in Blender - of course if anyone is interested, in cuch case, please let me know in comments and stay tuned :)
Cheers!

Material preview - some quick 3D scene made in Blender to preview this material. The tree was generated with its free tree tool.
PBR preview: Albedo / Normal / Height / Roughness / Ambient Occlusion - AspectRatio 1:2
My current photogrammetry workflow used for this reconstruction (more details on my youtube channel: https://www.youtube.com/c/GrzegorzBaranArt
The source object - unfortunately I didnt document stuff very well at this time (it was captured over 5 or 6 years ago) so this is the best context picture I have :)
Metashape - photogrammetry reconstruction based on 167 images.
Blender - low poly model alignment for further PBR bake. I used the same technique as I use for terrain (mode in the video below). This one was more challenging regading of proportions and alignment as instead of plane I used cylinder
The video where I explain the technique I used to align lowpoly model over highpoly one for baking

The only difference is that this time I used properly scaled cylinder instead of plane to get 1:2 Aspect Ration coverage
The material and texture-set was added to my material's library:
