Hi,

Would someone be so kind as to lend me some suggestions with this render?

I am having problems getting light through the glass in the windows.

 

I have placed two omni lights inside the house and have add materials to internal walls

so that I could get some light to bouce around.

 

The glass on the windows is an arch and design material (see screen shot).

 

I am using mental ray with a Daylight system.

 

Thankyou for your help

Typically I like to set the glass objects to "Pass Through FG" and if your using Photons then turn OFF "Generate GI"

 

These are set in the object Properties -> Mentalray

 

Quick question, why is Translucency turn on for the glass material ?

Hi Justin,

thanks for that, I will try those settings

 

Why is Translucency turned on? Well, I thought that it had a similar effect to Transparency? According to the Mental ray docs, there is a difference.

 

 

 

Translucency here works in exactly the same way as the Translucency shader. It allows a surface to be diffusely lit from behind, in the way that frosted glass is back-lit. The higher the translucency value, the more the back-lighting effects the surface. (For more information, see the Translucency shader.)

 

 

 

Cheers
