I'm creating an architectural rendering and I would like the inside of the house to be visible, yet, I want the windows to be closed because that's what I was asked. The problem is, with Sun strength set to 5 the insides look very dark if seen from the outside (see swimming pool area). If I want the inside to be illuminated like in the first picture, I have to set the sun strength lamp to 20. The lamps on the inside have not been touched between renderings, but they don't seem to be enough.
I have clamp direct set to 0 and clamp indirect set to 4. 2000 samples. Filter Glossy set to 1 The glass material is set like picture number 4 Background (enviroment) has a strenght of 1.2
Is there a way to achieve the same light from the inside and the outise in just one rendering?
(Also any advice on how to make the sky look better is higly appreciated)
