Why does PPV darken scene?

So, I figured it out. When Blend Weight of the PPV is at 1, and the Min/Max EV100 (using Extended Luminance Range that activates EV100 units) are each at 1, it’s darker than outside it. At 0 Min/Max EV100, it’s the same lighting as without the PPV, and also as viewing into the area from outside the PPV when it’s there. I also noticed that the Lightmass Importance Volume causes a brightening effect or smooth transition to brighter when I’m just inside it, but not inside the PPV (with the Min/Max EV100 settings at 1 or 0). However, when entering the PPV, it quickly transitions (but not instantaneously) to the lighting inside the PPV. Now I have two questions:

  1. Is Priority of the PPV able to override, mix, or remain secondary to the Lightmass Importance Volume? secondary meaning the Importance Volume overrides the PPV if it has a higher priority set by a value or another way.
  2. Does the Lightmass Importance Volume have an auto-exposure system in it? or is it merely displaying the concentration of photons in the area it covers?


Outside PPV, Blend Weight = 1, Priority = 0, Blend Radius = 0, not Unbound


Inside PPV, Blend Weight = 1, Priority = 0, Blend Radius = 0, not Unbound

Yours is getting brighter inside the PPV, then, @KhappaMJ?

My guess is it’s either Exposure Compensation is higher than 0, Min/Max are lower than 0, or if using the camera…it’s a different setting.
