As I said, I know there’s a lot wrong with it, especially how sparse it is. At the moment it’s Blender practice (I come from a C4D background, and interiors work very differently between the two). The background is simply a placeholder, and the room itself is very much thrown together. My interest is materials and lighting, and I know that both still need work (hence in WIP). For example, I hate the stairs at the moment, but they have potential.
And I tend to use my eyes as reference. I look at the room I’m in, and draw from that (I’m not in that room).
I am, however, interested in what you say about 2000 being too high. Anything less is grainy to the point of horrible, even with clamping. The scene at the moment has the HDRI, one sun, and three emission shaders (one at each window). I understand that internal is going to have more grain than external, but how do I get down to 1 hour and retain quality? GTX670.
By comparison, this is an interior I did in C4D.
