Multiple Cameras in Unreal 5.5

Hi everyone!

We’re making an installation in Unreal 5.5 with skeleton tracking and need the best tracking possible.Our plan was to use multiple cameras and the ZED SDK.

Is there a known method for getting multiple cameras to work in Unreal?

Has anyone managed to get it working?

Can you see in Unreal if there are multiple cameras being used for the tracking?

Thanks for the support! Either way I’ll keep the community updated on our solution :slight_smile:

Hi,

You can use our livelink plugin to use multiple cameras in Unreal.
However, this only gives access to the skeleton data, not the images or anything else.

Sorry, the link did not work.

You can find it here : Live Link for UE5 - Stereolabs

Will check out this solution! Is it still possible to check the image from the webcam through the Unreal Plugin?

No, because the ZED SDK already uses the camera to compute the body tracking and can’t be opened twice.

One more question, does this work with Unreal 5.5? I noticed the latest release was older.
Any issues we should be aware of?

I tested it with UE5.5 and it works for me.
I have to say a user reported a crash with DX11, but upgrading my GPU drivers fixed it for me.

Yes, I’ve managed to get it working in 5.5 as well :smile: The tracking is really snappy, we’re very happy with the result.

Does this work only in editor or in builds as well? How does one set up the LiveLink setting in Unreal when packaging?

Thanks for all the support!

Thanks!

The only limitation is that you have to build in “development” mode, not “Shipping;” otherwise, it crashes.

You can use a “live link preset” (https://dev.epicgames.com/documentation/en-us/unreal-engine/using-live-link-data-in-unreal-engine) to setup your project in advance so it automatically connects to the right source.
