Gothic brick structures WIP

There is a proof of concept for my new system of creating brick masonry wall. Every single brick (and the grout obviously) was a separate geometry, before I baked it onto a lowpoly model. The random input blends 25 sets of PBR seamless textures of single bricks. (Yeah, I made close-up photos of 25 single bricks, then turned it into seamless ones, and added some magic to create also roughness and high frequency bump for each brick).
ToDo's:
- correct the distribution of the bricks, especially the arch keystone
- make the pipeline quicker and more efficient
- add some automation (maybe a batch script to bake the output files)
- allow to make repeatable elements
- create more elements like round windows, doorways, arrowslits, buttress, machicolations etc.
- create more single brick textures (40 should be fine)
