Hi,
I've encountered an issue in refractions. (Alpha 6 14-04-2014 daily - Max2014)
I have a large model in Max modeled in meters (modeled with Autocad + Rhino in meters)
I created some thin glass panels 0,01-0,02 meters thick (1-2cm.)
On these thin glass panels refractions and absorptions are wrong rendered if the thickness is 0,01 or 0,02 meters.
If I change the thickness to 0,03 these panels are rendered good.
The absorption creates a strange effect on these panels, a sort of circular area in front of the camera (also on the left-right side)
Soon I will post some screenshots.
regards

what is your overall scene size?
-
you have the scene
I enlarged the base to 20km, 20.000 meters
-
is the IOR the same for the green-tinted glass and the white one?
-
ewww, 20km with 1-2cm details ;) This sort of scenes will always cause troubles, if your details are on the edge of the scene

I understand if this room is far away from the center but it stay on the center, more or less.
Imagine to create a fly-through animation with the country all around the building...
20 kilometers are nothing. I created larger masterplans with vray.
Probably Embree can't handle tiny and large details in the same scene.

Fixed cases when the detail is not too far from origin.

many thanks!
