I have also tried overriding the 'Direct visibility ovverride' in Environmental overrides just to see if I could get anything to show up with no success. I did recently update 3ds max and did not have the problem prior.Įdit: Other things to note.I have played with the exposure and it isn't a matter of the HDRI map being too dark. I am using Corona 1.5 (hotfix 2) and 3ds max 2017. I have tried both the Max environment slot and the Corona environment slot. I assume there must be a difference in environment / exposure / camera settings between the two scenes but I can't pinpoint what it might be. I opened a different scene and don't seem to have the same issue. The map does not appear in the beauty pass of the Corona frame buffer or in any file format that I export. I can see the map in reflections / refractions. I have a scene that will not render the direct of my HDRI map.
