If you want it for free send me a message on Artstation introducing yourself, I like connecting with people :)
I wanted to share this tutorial I made in my own free time, regarding the Normal Edge decals, as I mentioned in the pdf I don't want to take credit for this technique, I'm just explaining in an understandable way, This first saw this technique in Hitman absolution that was developed from 2009, Nowadays many games and studios adopted in their workflow. At the end of the pdf, I link all the resources and link that are already available online for a better understanding of the topic. I hope it will improve the quality of your environments allowing you to focus more on art.
