TechBuilder is a collection of ~200 sci-fi parts, sold by KuhnIndustries on TurboSquid. He’s offering a ‘light’ version for free on Blend Swap.
I just finished building/compiling a huge collection of Sci-Fi stuff. I’m selling the full version, unfortunately, but I figured I could post a few samples for free :) A few parts are included from previous projects, but I’d say 90% of this is original geometry.
If anyone’s interested, the full version of this file can be found here.
