Today, my company published a blog post that I wrote about our decision to switch from Unity to Unreal for an under-development mobile game called * *.
We also published an earlier, more technical UE4-related blog post about Blueprint, written by our lead developer:
Very awesome blog post ! A very in depth look at how your progress with has gone so far. Keep up the fantastic work and hope to see more of your project as you progress along with the development of your project.
This was a really good read, it was also pretty impressive going from the Unity shot to your current UE4 shot.
Thanks. Yeah, Unreal’s physically-based rendering gets a lot of the credit for that. The other factors it that our artists were much more comfortable working with materials in Unreal, so they were able to get the look they wanted. Our programmers like UE4, but our artists are in love with it. 
Glad to see you on the forums, ! is looking awesome
