This is something I get in 2 days at work dealing with Blender Eevee in 2.8 for the first time.
The thing is I concentrated more time programming #animations for the lights and the pipelines shader (shadeeerrrrrssss! You know me) where you can see #energy going in an sh*t... Anyway here is a snap of my current scene!
Since Eeve seems to not be able to render UHD or crashing when rendered frames exceed 2K on my 1080Ti, I decided to swith up in Cycles to render a frame for prnting. The output image is around 11'500 pixels by 7'900 pixrls and was printed on 100x80cm matte paper.
