Library of photogrammetry based PBR Environment Materials by GB

This product is a life-long* access to the library ofmy best 4k photogrammetry based PBR materials with the extended commercial license for each included.

Actual amount of photogrammetry based PBR materials available in the library:

'92'

By purchasing this product you get not just a full life-long* access to the library of high quality PBR environment materials I already made but also to these I am going to add in a future.

Currently the library contains over 90 high quality photogrammetry based PBR materials with the market value over 400USD and is growing.

I am still thinking about the form it is being shared as I am not sure would it be better to keep materials in large ZIP archive files or as it is right now available one by one, but time will tell.

Currently each material is stored in alphabetical order
as 4096x4096px

- 'SBAR' - a Substance Designer file with all textures contained (all channels are 8 bits except the height which has 16 bits).

- 'ZIP file' which includes Albedo, Normal, Height, Roughness, Ambient Occlusion maps (all stored as 16 bit PNG files)

- 'JPG' - additional preview render file rendered in Marmoset Toolbag

- each albedo was calibrated using XRite Color Checker

- each material represents roughly 180cm x 180cm of real space (different coverage if happens will be marked with the name extention '_1M' for 1x1 meter, '_40CM' for 40x40cm etc.)

- newest materials added after October 2021 contain additional 32bits height map stored in EXR format

* tree bark materials are exception as were intentionally designed in 1:2 Aspect Ratio (2048x4096px resolution) for better use when applied to tree trunks

or more detailed material breakdowns for each of these on my Artstation profile in material section:

Every new photogrammetry based material I add to to my arstation page, if meets the quality standards I set for them, is going to be added to this library.

This library already contains set of high quality PBR materials worth around 300$ on Artstation Store.

* by life-long access I mean that everyone is going to maintain access to these materials through this library as long the gumroad exists, but everyone who purchased access can download all existing materials and keep using them forever.

Question&Answer:

Q: You captured hundreds of materials, why didnt you add them all?
A: I added just these materials I was sure they met my quality requirements. For example some of my older materials was stored in 8 bits only. Some werent correctry calibrated. Some were too glitchy. I am planning to rebuild these materials in a future  and add them after they are fixed.

Q: Why do you keep these materials this way without adding them to a fancy webpage?

A: It let me keep the lower price as I dont need to pay for a webpage or serwer maintenace. But if you prefer to purchase them using fancy webpage, all these materials can be purchased through the Artstation Marketplace where each costs 4.99USD.

Here is the link to the artstation marketplace: https://www.artstation.com/gbaran/store

Q: How long do you plan to support this product?
A: It depends how many people purchase access to it. It might be months, might be years as I still plan to keep working on my photogrammetry research and these materials are part of it. But no matter how long it is supported you always win. As even if I would stop tomorrow, the library already contains content worth over 300$.

Q: Do you plan to add procedural materials here?
A: No. I want this library to be purely photogrammetry based. But I consider to add to this library sets of photogrammetry based atlas textures in a future.
Q: Does every material covers exactly the same real space?
A: Most. These materials which covers different space to 180x180cm are marked and named differently. For example wood which covers 1x1meter is called 'gb_wood291_1M'
