4.1 is still in QA testing at Epic Games, that’s why it not release with the launcher update yet.
Is there a way to get Substance plugin to work on 4.1 preview build? Because it only works with 4.0.2. I have posted details about that problem : Adobe Support Community
Please Epic, find a solution with allegorithmic. Thanks.
You made a small typo
Great Job! Keep the up work the best!
Im really loving working in Unreal. Its a such an artist friendly editor. Well done.
One thing I have noticed that Unity is making a whole lot of deals with the likes of Enlighten, and Speedtree. Is there a possibility that Unreal can reach agreements with these plugins also, or at least offer a cost competitive integration.
Keep up the good work
Whoop Whoop! this is going be ! I just my setup can run the elemental demo hahaha! Thanks Epic!
A Scene Outliner Folder System very helpful thing for level organisation.
And many other good things will came soon. Thank you 
EPIC’s
Hi Guys,
Any chance you can get texture atlases going again in 4.1?
I’d love to rebuild my multi-biome landscape material in UE4…
Was hoping to see a way to copy location coordinates for a mesh in this update, like we could in the UDK. Maybe next time? =(
Well Epic did say during one of the recent TwitchCasts that they were going to start doing same day updates to the git. One really good reason for doing so is to ensure anyone making fixes to the source are up to date as to what was fixed and not repeat already done work.
Personally I think this is a great way of doing it just as a motivational factor. Having your fix in a AAA engine is hero pie stuff.
4.1 is releasing this week correct? I need a date! :mad:
They said later this week, which is probably Thursday since they release most of the demos on Thursdays. 
There might be another Twitch Stream on thursday, I think they will release if afterwards.
I wont be able to play with it till Saturday since Unreal Engine killed my GPU yestarday so I need to order a new one on Friday for Saturday delivery
