GPU progressive lightmapper

With both Unity and Frostbite working on their respective implementation of a GPU accelerated lightmapper, I hope that Epic also considers adding such a feature to UE4. Given how long we’ve been stuck with the painfully slow lightmass, an interactive lightmapper would be a godsend! It can’t be overstated how much of a game changer this would be for every single lighting and environment artist working with the engine. Just imagine having instant visual feedback rather than waiting for minutes or hours!

That will happen when pigs fly since Epic only cares about Implementing things that they need for their own games
