hi! welcome aboard.. This kind of effects needs more time of a simple 50% transparent settings. First one: the illumination...the scene need to be rendered with a good light source as HDRI and a direct light, I see a sun behind the building so the scene has been illuminated first without transparen...

Hello,

I would like to rebuild the x-ray view (preview file attached).

I've already tried to use half-transparent materials with blue colors, but I did not get it right.
Do I have to choose some special render settings? Which material would be best?

Thank you!!
