Hey Dan,
this allready seems to be helpfull, to at least get the first design right. Even though, being only able to tweak stuff inside the BP editor isn’t optimal, but should work out.
What would also be great, if you could somehow bake navigation information into your blueprint, so you could use UE4s Navmesh system with procedural generated content, that you generate using class blueprints.
To my understanding it is both. The votes are a pointer towards epic, so that they can see what the community desires and considers those wishes into their release plans.
It would generally be great to see more tools in UE4 that are catered towards procedural generation of content, like integration of Noise generation like perlin or fractal noise.
A lot of indie games generate their content procedurally so this could really help to make it more feasible towards indie devs.
