The shader has been updated accordingly to the latest SP changes .
- Added Support for VT and mip-mapping
You should also use Temporal AA, it works really nice with my importance sampling algorithm, removing a lot of noise and jittering.

How about PBR?
This blog contains my vision of how PBR should impact modern games, from both point of view : as an artist and as an engineer.

Substance Painter UE4 shader update
As you all know Allegorithmic has broken all of the custom shaders due to changes in their architecture.
So far I have updated the shader for UE4 and uploaded it to the share, but it takes time for Allegorithmic to review uploaded files.
You can use my shader without Allegorithmic's verifications from here:
UE4.sp2018.2.1.glsl

Unity 5 shader for Substance Painter
Here is SP viewport shader that emulates Unity 5 BRDF:
Download from Google disk
It's not 100% match unfortunately, but close enough.
It is how GGX-based BRDF should work, not how it works in Unity.

HDR vs LDR Image Based Lighting
During my
work as Technical and lighting artist, I was asked by level art team: “why we
can’t use LDR images as skyboxes, they are so fancy and handpainted, why not?”

Update for SP shaders
Re-writing some of the SP shaders to filtered importance sampling, looks promising:
Default PBR-metal-rough:
Iray reference render:
New filtered IS method:
Looks like that rough metals are the most affected.
