I used the raw power of the Titan RTX to do these renders inside Substance Designer. From baking, to texturing in Substance Painter, to rendering in iray, its entirely RTX fuelled Substance.
The AK74 uses 3 8K udims, the M16A1 uses 2 8K udims, the magazines and ammo casings 4K, and the bullet tips 2K.
It was a pleasure working with Nvidia and Allegorithmic to dive really deep in what change RTX brings to the world of texturing.
PS: I will change these renders up a bit, they originally had a dark gray background, and ill add some nice Escalation 1985 banners.
