I thought that looked like the UE4 material editor in the material breakdown you posted and was curious about the engine change. Good luck with the transition and looking forward to seeing some screenshots out of UE4.
http://www.allegorithmic.com/substance-ue4 The plugin for the UE4 just came out, if that helps at all. I haven't gotten to trying it yet, but at least you don't need to recompile the engine now to be able to use it.
I would like to point out that UE4 took a lot of things from CE. They can surely give a match to UE4, just wait what's up around the corner, you may be surprised.
