I don't know if this is how it's supposed to work, but:
I'm using the physical sky feature as the GI override material, and trying to use an HDRI as a reflection override material. I understand with the physical camera you're actually adjusting the exposure of the image, so you need to increase the multiplier on the HDRI to get it to match the exposure.
I've found, though, that you have to adjust the multiplier in the VrayHDRI material slot (in my test, setting the multiplier to 100 works) and leave the multiplier in the reflection override slot at 1. This makes it appear fine as both the reflection enviro and the background image.
But, for some reason if I do the opposite and adjust the multiplier in the Relfection Override slot (to 100) and leave the VrayHDRI material multiplier at 1, it seems to have no effect on the brightness/exposure of reflections.
Is this how the multipliers are supposed to work? There's no real work around, you just have to remember to use the multiplier in the VrayHDRI material and not the one in the override slot.
