Library of 4K Alphas and ZBrush Brushes - by Grzegorz Baran

A material related library which similar to the environmental one which I am also planning to grow and develop in a future. This is the library of ZBrush Sculpting Brushes and Alpha Maps:

Brushes should work in ZBrush version 2020.1.4 and higher. I cant bring backward compatibility to 4R8 as its not supported by Pixologic and cannot be activated anymore, but I am not sure if it would have any chance to even try as every ZBrush user can upgrade it to the most recent version for free.
Similar to my MATERIAL LIBRARY, this one is also a life-long* access service which gives full access to all existing but also to those which are going to be added in a future. Currently this library contains '111' photogrammetry based ZBrushes and '105' 4k 16 bits seamless alphas which can be useful to sculpt rocks or wood on your 3d models using either blender, zbrush, substance painter, 3d coat, etc.
I plan to cover even more rocks and cliffs, some wood and fabric etc.
In long term, when the library reaches certain amount of alpha materials and brushes I plan to increase the price for access to it as it already happened with a welcome price. So I encourage everyone who is interested into getting high quality content to join.
Feel free to drop me any feedback as in long term it helps me a lot to improve the quality of my products
Big thanks for your support,
