Unreal Engine Livestream - Live Link 4.20 Updates - July 12 - Live from Epic HQ


Introduced in 4.19, Live Link is a feature that enables you to connect Unreal Engine 4 (UE4) to your DCC tools and allows you to stream data into the Engine in real-time. This enables you to preview animations in your preferred tool, directly inside the Engine without having to go through the export/import process, giving you more time to iterate on your content and less time exporting and importing into the Engine to see your changes.

In this stream, we talk about the changes made for 4.20 including support for Motionbuilder and the ability to use the new Live Link Component to automatically establish connections both in the Editor, at Run-time and even in packaged projects!

Thursday, July 12th @ 2:00PM ET - Countdown

If you have questions for the folks on the livestream, feel free to toss them in the comments below and we’ll try to answer them!


[Question] Are Maya blend shapes supported or is it limited to bone based facial rigs?

It’s Amazing!

Will this update World Composition. You keep saying that you need to?

Does Live Link support 3ds max?

[Question] Will there be support for Blender developers?

Having trouble finding Live Link blueprint nodes. Could you reveal how to find nodes like “On Live Link Update”?

Will live link support Maya LT?


@Wes Bunn: For some reason my question wasn’t picked up in the stream. I wonder why? It’s not like you ran out of time and there are only three questions in this thread!

So I’ll ask again: Is there support for blend shapes? Thanks!

I thought we touched on this, but in any case, Blend Shapes are currently not officially supported out of the box.

The architecture is set up to allow this though it’s not actually hooked up in the Maya or Mobu plugins. We need to make some code changes on our side to support this. I don’t have an ETA as to when those changes will go in, but will update this thread after I’ve gotten some more information from our devs.

Thanks a lot for the detailed answer!

I would do anything to figure out how to get livelink on a mac with Maya and Blender

this event was something incredible!

Wes, your Livestream for LiveLink is very helpful. I noticed that when you connected Mobu to Unreal in that vid, the skeleton didn’t turn 90 degrees when converting from Y up to Z up. In Maya I am dealing with that rotation.

Do you have any recommendations on most efficient way to work in Y up Maya and see anim Z up in Unreal?
