Hi I saw this recently : UE4 + Spout + Resolume Plugin Proof of Concept - YouTube
And there is this studio here in Montreal taht built there software with Unreal Engine : http://immersivedesignstudios.com/
But the thing is for my job i’ll be on MAC and there is no compatibility with Syphon or any plug-in or built-in feature for video mapping for Unreal Engine. It will be awesome, I know that your money comes mostly from games for mobile, PC and Console, but there is so much potential in Unreal and so much markets. And honestly I don’t really like Unity even if there is better tools for mapping like a syphon plug-in. http://syphon.v002.info/
So just asking for some video mapping features for Unreal: heres to facebook groups that can prove a little bit the potential; VJ Union Global and Unreal Engine Live Visuals
Thank You
