Thanks! For resources the most helpful were the OpenGL Superbible, learnopengl.com, Foundations of Game Engine Development Volumes 1&2 and the 3D Graphics Rendering Cookbook. Then there were also a lot of web sources that were very helpful such as the Google Filament PBR paper and some realtime rendering presentations from other developers.
