Yesterday I've jumped on the K3 OB train, and decided to make some test.
Here's my first empty room result: And K3 settings: Oh men, when K3 will be ready, it will be an awsome tool!! The gi accuracy is perfect. Working with VPR and realtime tone mapping: Light setups of my scenes will be much-much easier!
Bdw I've met some strange thing:
- When I load the scene and hit K3 render or K3 VPR, the Ks PhySky's Turbidity value won't render correctly. I've set it as you see to 1.9, but it renders with about 2.0. After hitting render and stop it, I'have to modify the Turbidity value and hit render-cancel again. After that I set again to 1.9 and it renders correctly
- LED stripes on the ceiling is an poly with 1000% Luminosity. K3 VPR does not show changes when I modify the lumi value even if I hit clear gi, build gi, reset, save object. Only if I exit LW and restart the scene
- Some random crash (I'm trying to reproduce them)
Of course this is an online beta, and I absolutely not complaining about anything. This is NOT a final product, PLUS I don't know how to setup things for speedy K3 render, so the rendertime at 3840x2160 resolution on my i7-5960x@4.4GHz is 4h44m. So currently rendertime informations are not so important. My "limit" for a final render is 1 max 1.5 hour. Here's a 1 hour K2 render from the original scene: Yes, the K2 1 hour render has very crappy GI, but deadline is a serious thing.

Is anyone interested starting finetuning K3 settings? Maybe I can upload the scene (the empty one - first pic)
