I can't believe I loose my KT project. 
Early afternoon I put it to render a 1080x1440px image in MTL mode and after ~2h I decided to start and load the Substance Painter project to check some parameters and after a couple of minutes my system froze and I had to reboot it. Now the KT stops load the project at 65% (the file is 67MB long, hard to load in a editor)
I think the processor got too hot since the memory load was at most 70% compromised. The cooling fan was running at full speed.
My backup was out of date. As the scene was built into Kerkythea that will take a time again. Maybe this time I try to setup the most I can in Wings3D project.
