Yep, bit by bit we move closer. Also, Talad is in the process of organizing all of PS's code to port to UE. With millions of lines of code, it's quite the task. The more code that can be brought over "as is" the faster it will go. But certainly a lot of the CS related coding will have to be rewritten or adjusted to work in UE.
So far we have the obvious stuff like maps, characters, a UI, char creation -> character into the world and all that goes into that, then engine stuff like scripts for combat, magic, crafting, quests, etc. Then eventually expanding the UI to interact with it all. It's a LOT, but piece by piece we'll get there.
And keep in mind that UE4 was designed much more for first person shooter games and not MMOs. So some of these things are real challenges that haven't really been done before. Big props to Talad and ravna for digging into this stuff and working it out. And to Venalan for working on the map improvements. And to Eonwind for working on a linux build.
And cool character shadows by the way.
