OOOH. Now I get it. I wasn't refering to Blueprints persay. This is a Blender thread after all.
I was refering to Animation Nodes addon and Sverchok nodes for Blender all in the up and coming realtime viewport for procedural generation and driving on the fly. Blueprints in Unreal, as he said, will always be a realtime event based environment designed for gaming. Houdini did try to splice into Unreal Engine like what Fabric Engine was doing, where you could build procedural worlds from Houdini right into UE - by code it's possible, but they seemed to stop developing that.. A future release of Unreal Engine will have nodal and stack driven particle effect that look bonkers; but for realtime driving of 3D visual data - Blender is getting better and Houdini is unmatched and Fabric Engine dead and others like Notch are pretty lowkey but functional.
Just to tell you what I'm on about, here is a realtime volume render of a Mandelbulb in Eevee and created and driven with Animation Nodes.
