    Drat! Found a wiggly in point Ten already

    I'll make an official report but always like a confirm in case there's some new switch I've missed.

    Anyway, scene is using an HDR. When cam pans over to where the HDR sun is, it shows through when Enable Volumetrics gets turned on. The object it's showing though has geom & even turning on Double Sided had no affect. Just standard material at this stage. No Glossy Reflects, RT Only, Spec & Gloss at 0. Light has Shadows Enabled which was the issue before with Point Lights.

    Bottom Line: Can't use an HDR w/ Volumetrics.

    Just opened the same scene in 2019.03 & it does the same thing. Of course that scene was saved with 2019.1.

    Alright then. Figured out what's going on.

    This is by "design".

    From the Wiki...

    "The Use Backdrop Color option causes an object to blend in with whatever backdrop you have set, including a background image. This can have the effect of making objects appear slightly transparent. Use this option to simulate the effects of an underwater environment or a hazy, foggy day with an appropriate Backdrop Color like bluish green for underwater and grayish white for a foggy day."

    That's a pretty wishy-washy description, but essentially this should pretty much always be OFF for anything above ground. I've toggled this setting On&Off for years frankly never understanding what it was supposed to do 'cuz I could never see any difference.
