I never claim it to be hard, just to be clear. Its just a casual remarks that the time spend on making UV for lightmap can be used for content creation. 
Also its not a criticism towards Epic (if that’s what people think. Can’t believe I need to clarify …but well)
Hoping to see whats installed as well. I am still new, so I am not even touch the surface, so even if there are mayor changes, I may not notice, LOL. In any case improvement for efficiency, performance, features, ease of use are no doubt welcomed.
Cheers.
