Hey there, we actually have a lot of experience in this area. We have developed the 3D web configurator for the largest playground manufacturer in America over the last year or two as well as maintaining it with product and pricing updates: http://design.backyardadventures.com
For VR configurators I believe we we created the very first VR car configurators built in UE4 back in 2014: Audi Car Configurator VR Showcase on Vimeo and have been working in VR ever since
We have also been heavily involved in making UE4 the norm in the Arch Viz world, also starting in 2014 and our latest tool was built for CBRE: Commercial Arch Viz Demo on Vimeo
We always get excited about the chance to work on products that push the boundaries of the non-gaming world with gaming tech so I’d be thrilled to chat more with you about this. Before speccing this out it would be great to have a quick call so I’ll email you now and setup a time.
Thanks
