How to live stream to Twitch from within version 4.3 of the Editor

I just downloaded the binary/packaged version of the Unreal Editor 4.3. On both the OS X version and the Windows version, I don’t see anywhere to setup the Editor so it will stream to Twitch. I see there are live streaming settings in the Editor settings; but under the Plugins section of the Project settings there is no Twitch plugin.

Do I need to compile the Editor from source to get access to the Twitch streaming, or is there somewhere I can download the Twitch plugin? Or am I just missing something?

Would like to know how to broadcast, too, there is no icon in the upper right

Just a quick bump for the question. I haven’t seen or heard anything on Twitch streaming form the Editor in 4.3. Did this functionality make it into this release?

Turns out the actual plugin didn’t make 4.3, but is available in the master branch.

Here is the forum thread I asked in earlier:

So if you are comfortable downloading the engine source and compiling, look at \Engine\Source\ThirdParty\Twitch\InstallingTwitchSDK.txt for instructions on how to get going.

Thanks for the info. I’ll have to check that out.
