Forest Ground - Photogrammetry based Environment Material

First scan this year!!!
I used this one as an opportunity to research some other options and get rid off ZBrush from my workflow. I dont want to use ZBrush anymore as I dont agree with Maxon price strategy and I am not going to pay almost full product price for just a single year upgrade - especially I paid full price already.
Luckily Blender can do the job very well, if not better. It can easily preview vertex paint and has amazing geometry projection tool which is very useful for low poly model alignment - similar to what projection tool does in ZBrush. I might drop a video about it on my youtube channel if anyone is interested in details.
Of course the scan itself didn't go as planned, which proves the point that everyday practice matters a lot. For example I forgot to align the polarisation filter, so the entire capture was taken with 45 degree half cross polarisation. I also forgot to switch the camera into MANUAL mode, so this entire capture was taken in apreture priority mode. Somehow use of tripod saved the day and after some photo-editing the result turned pretty well, therefore as promised, I added this material to my material's library:

Source location - as you can see this surface coverage wasnt large enough to cover 2x2 meters but I used ArtEngine to generate missing data

Source - surface depth with my shoe used as a height reference. Good luck trying to mimic this level of complexity proceduraly ;P

Metashape - 100mln poly heavy photogrammetry reconstruction with camera position preview. As you can see I didnt shot dense over grass as I already knew I am going to cut it. I just needed this part for ruler I could use as a reference for 3D cropping.

Substance Designer is still my favourite texture baker as it can handle heavy geometry very reliably.

ArtEngine seam and grass removal - the purple area is the area I marked for the ArtEngine to get it reconstructed with use of remaining data. It was grass and some other crap I needed to get rid off.
