How to Create HDR Environment Files for Dynamic Scenes?

Found this old forum post on creating dynamic reflectionTexture using ReflectionProbes, with a PG. For some reason it wasn’t completed.

The PBRMaterial.roughness is ignored when using reflectionTexture. And reflectionTexture.adaptiveBlurKernel does not work, like in MirrorTexture. This makes ReflectionProbe only useful in very limited use cases.

So how does one blur reflectionTexture created by ReflectionProbe?

Is this still the current state @PatrickRyan?

I might experiment with this Camera approach (though not sure yet how to handle perspective distortion and joining seams automatically):

  • place a camera in the middle of you World Scene.
    • rotate it 90 degrees:
    • Make screenshot:
      • 4 shoots in four directions ( X, -X, Y, -Y )
      • 1 shoot up
      • 1 down.
  • repeat the process 3 times in your scene
    • 1 time underexposed ( going for shadows )
    • 1 normal lit scene and
    • 1 overexposed ( highlights )
  • process the 6 separate LDR images to 3 Cubemaps
  • pack them as one HDR Cubemap
