im hoping for skin shader improvement as well, and the most thing i want is something with lightmaps to happen, either remove them or a more simpler solution, like cryeninges.
Just to make the point the Cycles render engine is open source even for commercial use, created by Brecht van lomel who just got persuaded to leave Blender development and go work for Arnold renderer. But the engine in there and ready for use, even for commercial projects at no cost. Dump lightmass, Integrate Cycles!.
Cycles even has a standalone code version now that doesn’t even need Blender to run. It’s a no brainer, As far as im concerned Lightmass should of never even been brought into UE4, it’s the weakest link in the chain of the whole code base right now.
