Library of photogrammetry based PBR Environment Materials

This is the library of PBR environment materials I scanned and found good enough to share:

By purchasing access to it, you get 'life long' access to these which are already there but also to those which I constantly add.
I plan to upload every new scan which meets my quality requirements to this library so everyone with the access should be able to download it at the same time it is published on my Artstation profile.
I believe I set a fair and affordable to everyone initial price. I might change it in a future when the library grows.
Currently library contains 79 materials I sell on Artstation Marketplace already with their total value over 350USD and is growing.
Bear in mind that since running my youtube channel is quite expensive, by purchasing access to this library you help me to to fund part of my research and in result to create even more content I can share with everyone on my youtube channel.

Feel free to ask if anyone has any questions, will try to add answers to the QA part at the library description.
Big thanks for the support and I hope someone finds it valuable
