Photogrammetry Pine Tree Bark Material

Hi everyone, I'm excited to share a new tiling photogrammetry tree bark material that I've been working on for a while now! Been trying to incorporate more photogrammetry into my material creation process so this was one of many experiments I've been running. Still not where I want it to be but I certainly learned a ton and will keep refining the process as I continue! Images were taken with a Canon Rebel, the scanned mesh was generated in Agisoft Metashape, I did a bit of polish and tuning work in Substance Designer and Photoshop as well. Final renders were done in Unreal Engine. Tested in UE5 via SpeedTree but will need to do some more work before I am ready to show those off :) I also tried the same workflow using Reality Capture to see how it compared to Metashape. Both seemed to have their strengths and weaknesses. Will need to conduct more test before I'm comfortable sharing my findings but overall they both were pretty awesome and gave me plenty to work with. Thanks so much for taking a look!

The raw scan was decent but definitely needed some extra love to get the result I wanted

These nodes were super helpful, they did a lot of heavy lifting

I was hoping to capture enough of the tree to generate a 1:2 ratio material instead of the 1:1 you see here but sadly I failed to scan enough vertical space to make that happen after vertical tiling. Next time I'll be sure to get way more overlap!
