Hi. Between (per project if you’re lucky) naming conventions, paths, custom properties, etc there are innumerable permutations to account for, ie automate. It can be streamlined by customising export presets or the exporter itself, but that unavoidably involves the project authors input.
As for VR you can diy things for now. I’d expect this or better would be achievable in Eevee.

The FPS style navigation could happen via the coming interactive mode. Else there’s tweaking the Shift F fly mode to hover above mesh surfaces at a fixed height (human eye level) etc, sells the illusion.
