Old scene with new Kray. First time possible to use displacement (brick wall) in normal scene (I think G. fixed hot photons).
Tone mapping: only Tanh.
Light: Physky without Sun + LEM in windows.

really nice uPDATE thank you (Y) .

It's a nice render, but the shadow on the white wall right next to the windows is very noisy. I'm surprised to see this noise a 31 minute rendering on your supercomputer at 1600 px wide - probably because it is full brute force path tracing.

Is it possible to optimise the render time using smarter photon gathering (sorry if I'm not using the perfect terms, but I'm sure you know what I mean) ?

Actually this scene is tough....also for V-ray. Please notice mirrors (dark). If I remember correctly V-ray took it twice longer.
Actually I put something wrong in settings.

Something strange happens with brick wall displacement in second image even the part not behind the glass plane.
It looks like displacement is shifted

This is just very poor settings for displacement. Only one step and low resolution sampling....test.

Well done.
Smooth and definitely better than in K2.

The noise near the window is the phy sky.
How to give lema there the problem will disappear.
It would be useful for a light portal and a problem.

Generally is missing one part left: Skyportals.
G. promised add them soon to Lightmap.
Then...Noise will disappear. Now simply is impossible and to reduce noise, we have to raise up amount of rays instead which means longer render...
