Sunny day in Seattle

If you turn on both reflect and refract GI caustics and use PPT that will calculate it like you want i think.

However the use of Vray:Caustics will often be quick but is best at caustics caustics for certain objects, not for doing say a whole room.

thanks daforce thats what i wanted to know

I'd over expose the exterior image a bit more

I am controling the image by rgb output, but it gets blocked by the window (( so i am affraid that if i overexpose it a bit more it would get blown out where the glass is missing...

martin, have you used caustics in this render?

i have activated the caustics in the indirect ill rollout to make affect shadows work.
