That’s a weird thing to say because online VR viewers like sketchfab are in fact based on unity. What “added value” over e.g. sketchfab has it to code you own VR viewer? Seems like doing a lot of work others have done before.

The shaders for realtime have nothing to do with keyshot. Keyshot is it’s own little render world that can’t be exported out in any way. You have to build your own shaders via texture mapping, it is a very different approach. Google pbr shaders
