Light not coming through my windows

[Boothand]

I'm testing out some lighting, just to help me get further ideas for the design. I was under the impression that sky-lighting would add at least some light entering my room through the windows. I even took away the glasses on the windows to confirm. How come skybox lighting doesn't enter through here? What are the criterias?

 

Placing strong lights outside my windows and targetting them inside makes the physical window seen from the outside seem very unnaturally lit up, not like skylights at all.

You may need to edit the sun position (if that's even possible) via the sky shader.

I've been thinking of that. Could solve the problem, but I was thinking... in cases where you want a sun higher up in the sky, there must (should) be a reasonable way to light a room realistically still. Normally, ambient lighting would come in through the window unless it's pitch black outside. Wanna work with realistic light sources here, so don't wanna make unique shaders for this room etc, too. Hmm.

Then you need -bounce 8 in your compile. This will simulate radiosity from sunlight. If you dont want to wait for that (as it adds a lot of time) then you may have to consider individual shaders for extra lighting.

You might be able to add light source to a glass shader for your windows, and still keep transparency.

I've already tried the bounce-8 and didn't have any visual effect in this case. I'll experiment with it more though. I'll probably go for using a lightimage with my glass shader though. The sun position had a small effect, but nowhere near a realistic result, for lighting up the room.
