By Humongous I mean the download itself is 1.99 GigaBytes in size. So you may want to consider if you really want it before downloading it .
403 PBR textures (403 .mtr files + 2054 TGA files)
7 Oily Films (will probably benefit from having their opacity reduced)
Total Number of included files & folders - 2500+
Extracted (from the 7z archive) size of the package - 2.89 Gigabytes
The PBR files for all textures are Diffuse, Specular, Normal, Height and Roughness. Additionally, a small number have Glow maps too. Each of the PBR Textures were com[posed by eye using ShaderMap 4.
If you do download it please read all the *.txt documents and I would really appreciate feedback so that I can improve on PBR texture creation as I am still learning. While I am quite confident that I know what I am doing when creating matt textures, I am not so sure where any reflectiveness/glossiness is concerned. Anyway the download is -
