I made this rendering using UE4. What I noticed is its really hard to spot the difference whether its rendered with something like vray or with any game engine. Although Interactive visualizations are really cool and we’re so lucky to have an Engine like UE4 but I personally think people of Industry require some time to absorb the concept that, that realistic looking Archviz can be realtime. Besides, Deployment platform for Interactive architecture should be smartphones or tablets(which needs some maturity in terms of hardware resources)
Have a look at my work I made its a rendered video instead of interactive walk through! Share your views about my work as well as topic of discussion.
