Physically Base Rendering (Real Time Ray Tracing)

[duckbill4375]

See the rendering below. When I Physically Base Render,  you cannot see inside the house thru most of the windows. If there is light coming in the room from another window you can then see in that room.  Other wise the glass on the windows just show a reflection. If I make a window a Pass-Thru with no glass you can see in the room in a Physically Base Render. What am I doing wrong?

 

It must have something to do with the property of the glass.  I checked the property and the glass is transparent.

The Physically Base Rendering requires lights to be on.  Be sure to have lights near your windows and set the number of lights in the render camera that it uses to a high number.

Hello Scott,

 

I did have lights on just inside the windows.  Any other ideas.

 

Thank you, Bob

Without seeing your plan, I'd say it's because glass is reflective and the amount of reflection will depend on the lighting inside and also the angle of the sun setting. Take it easy on the ambient light settings as well, too much makes a scene look flat.
