WebAs for porting old CG shaders to PPv2 HLSL shaders, the code you've posted has the right idea. You need to convert all CG blocks into HLSL blocks, use stdlib.hlsl instead of UnityCG.cginc, (and do the necessary cleanup that implies), and you will need to convert your scripts from a MonoBehaviour to a PostProcessingEffectRenderer.
