- For my curiosity, I'm reading sources codes of PBR shaders in graphics engines below.
- (a) Unreal Engine 4.8
- (b) Unity 5.1.2f1
- (c) Marmoset Toolbag 2
- (d) Substance Player 5.1.0
- I already read PBR calculations parts in (c) and (d), and reading codes in (a) and (b) at current.
- (d) was the most simple shader configuration because it only include shader files for shading calculations. ( Notes of Substance PBR shader - Gregory Igehy )
- (c) has some additional shader files for post processing (like SSAO, SSR, bloom), but the PBR part is very common with (d).
- Also the PBR part of (a) and (b) are also similar with (b) and (c).
- But (a) have so many shader files.
- After understanding (a) and (b), I may write short notes of it.
