UE4 shader for Substance Painter 2018.3

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.

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

My GDC 2018 presentation

HDR Image Based Lighting: From Acquisition to Render

Come visit my presentation on GDC 2018. I will talk about HDR image based lighting and how important actual "HDR" is for the final image. What is true HDR radiance and how to get it. Importance of photometric unit system in the lighting pipeline. 
I hope you will enjoy that!
