I have been working mainly on my group project of late in Unreal Engine and hopefully will have some stuff to post for that soon.
However my other ongoing degree assignment at the moment is to make a car paint shader in GLSL. So far I have been looking into BRDFs and PBR, and am still really in the early stages when it comes to shader code. However I have used this project as an opportunity to play around with the QT GUI system and have made a demo program for my shader. You can find the code on my Github, and see it in action in the video below:
