Is time to fix this and make working correctly.
I can not:
- build Photon Map and save it (small file which contain only PM information)
- build share GI (Final Gathering)
- build PM without rendering (this phase is short, should be no rendering) I get error in shared mode when press BUILD
I get stop (doing nothing) in Independent when press BUILD Actually only works INTERPOLATION mode.

Left are only procedures.

GUI menu.

I will post soon also very basic scene for testing.

Normal map renders wrongly. Standard grayscale bump render correct besides that is inverted (black/white)

Smoothing error in shadows.
Also visible when you activate Physky.

1. Visible slow render from Light Portals 2. Not visible background image behind window (LP block it)

White corners from LEM sources.

We have to do kind of “bridge” or more support for specular. LW2015.3. Now is freeze at 95-100%.

Everything about it in example renders from Kray and Lightwave.
You will see differences what is not supported/bugged.

One layer which is enable right now Couse crash (probably import from DXF or something that)

Two bugs:

1. Scene for research and optimization. Denoise OFF. Quality medium to see more effect of these pixels.

2. Corner Rays for 100 bounce lights setup but still looks like one bounce light.

tried reduce it but it looks like in scene are few problems.
There are some not supported connection in Nodes and also one wire (probably import from CAD) make problem.
Is nothing bad in K3, simply some parts making problems.
