As a test I created small enclosed building with no exterior openings with 2 floors above with no openings and a floor at ground level. I've also added in a site topo set 1/2" below the floor level.
On the interior of the building I made 2 set of rectangular walls, one inside of the other. I then added a curtain wall window.
When i walk down the hallway, I'm seeing the white Enscape site groundplane and the clouds and sky in the glass.
Can anyone explain if this is a known issue or what am I doing wrong here.
I have no interior lights.
First image is plan view of the building.
2nd is of the interior north interior hallway looking at the window.
3rd is same without global illumination.
Either way shouldn't see any sun or clouds in either of these.
Thanks in advance.
