Hi Jacob,
Glad to hear you're having success with the maya software.
We've demonstrated the UE4 & RT technologies at a few places, but we've currently kept distribution of the tech limited to a few studios for beta usage on very specific projects. In parallel we're in process of refactoring the real-time implementation on a Ziva plug-in framework, and optimizing for game engine integration.
Please stay tuned and we should have some progress to share in the coming months!
Michael
