sun rays added in post-pro..
Cool… If the suggestion here (Particle Effects) was implemented you wouldn’t need post production 
Fog is usually not achieved via particle effects. We already support visible light rays in fog, but that would require strong sunlight shining in the room together with a bit of fog - this is probably not desired for artistic reasons in this case.
Either way, the image looks nice! I would suggest to lower the bloom. We also lowered the default bloom setting for the upcoming version to give images a bit more sharpness. The bloom in modern digital cameras is pretty low and almost invisible in normal lighting situations.
I have the impression the bright daylight dosen’t affect the interior enough. Maybe the artificial lights are to strong, but I have this impression during my projects too and I ask me, could it be that we don’t get enough light trough the windows openings?
Here I tried to simulate it per postwork- more light in the near of the windows.
I tend to agree. I mostly use the white background so that I get a clean reflection of whats outside and I feel like its not the best.. but if I use the clear background lets say, there will be reflection of it on the window frame and curtains, even if i can change the background in postprod.
Your adjustment was needed, thanks.
I also think we don’t get the right lighting from the sun into the room, most of my project I have a hard time feeling the exact lighting. Maybe enscape could later on provide their own sun?
What do you mean with “provide their own sun”?
I think a reason for this could also be an issue with the auto exposure, which resulted in underexposed images with windows to the sky. This is improved in the current preview version and should maybe help here.
I would avoid white environments, because it cause a quite unreal lighting. It cause a lighting like you find in winter only, if outside anything is white. More natural lighting you get by a HDRI or the basic sky. If you look at a white room with one window, you can see the typical camera obscura effect - the environment is visible at the interior: the green of the grass is on the ceiling, the blue of the sky on the floor … and all the mixed colors of sky, plants, buildings between.
