Osiris is a starship design aimed towards stealth without invisibility. Rather than physically invisible - electronically so.
The main panels of the hull are coated with a slick 'grand-piano' like gloss, with procedurally generated hexagons embedded on each section.
The challenge with that was to learn how to unwrap the model so as to distribute said hexagons evenly and without distortion.
The hexagons are masked by a fresnel node so as to only be visible from certain angles - for instance, a glimpse of the underlying structure when the ship passes the camera. This can be seen in the video at 4k, though the effect is extremely subtle.
