Unless you absolutely have to stay in VW, I would consider looking into Unreal Engine. If you're adept at the 3d element of VW, it's really not that difficult to spend a few hours with some Unreal tutorials and then be able populate a first person Unreal template with a VW model via DWG export (of course that's just getting your feet wet). Then there's a plethora of tutorials for gaming hud/ui elements or plugins like HAL Archviz: https://www.unrealengine.com/marketplace/hal-archviz-toolkit-v1
