Blender is getting in bed with UE
Viewport materials and shadder integration are coming officially in Blender 2.8 with the viewport buff.
This along with improvements to a couple of Blender addons already in 2.78 makes for a very powerful asset creation pipeline.
This also makes for an open source (wink) of assets from a pretty large and professional community, all you need is an input white paper on community market for next installment.
