What updated workflows? Things haven't really changed that much in the last decade, especially not in games.. Yeah most "art" infused engines are custom and some you could even license (for an astronomical fee).. The state of Enlighten isn't an engine development issue, it's a UNITY issue.. There's nothing wrong with Lightmass in UE and it's far superior in terms of quality.. It's not like they just bought some middleware either, they made it... You think making an art package is difficult? You should try making an engine, a lot of it overlaps anyway with basic engine functionality and AFAIK the teams that work on said tools are usually very small. I also cringe at the thought of Blender slapped into the engine, irrelevant of what either one of us say that's the direction things are heading again with Source 2 / Epic with ART (Animation and rigging toolset) and CryEngines in engine design tools.. I'll just say it for once Epic are lightyears ahead in terms of engine development for their main platforms, it's not even a comparison at this point and it's not an opinion either.. An engine is nothing but a collection of tools, once they've finished optimising stuff and decide to finish off their experiment with 2D or Mobile then it could be a good move if they get a bit bored.. They already said they would update their BSP tools to something more intuitive for level design, so who knows.
