Troubleshooting Unreal Live Link for Maya plug-in

Below you'll find a list of common issues you may run into when using Live Link and their resolutions.

If you can't find your Live Link Editor window, it's possible it's been hidden behind the Maya window. This can happen if you restarted Maya while a the Live Link Editor window was already open. If this happens, move the main Maya window aside and click on the Live Link Editor window to bring it back to the front.

Camera focus in Unreal is wrong

If Depth of Field is turned off in Maya, you must manually set the Focus method to Disable in Unreal.

Character looks wrong / falls down in Unreal

If your character behaves strangely in Unreal, check to make sure its skeleton hierarchy is the same between Maya and Unreal. Live link requires the hierarchy and bone/joint names to match exactly. Also, Unreal only supports FbxSkeleton and FbxMesh nodes, so if your original rig uses other nodes you may need to make adjustments to ensure compatibility.

The Send to Unreal option is missing

If you don't see the File > Send To Unreal options, ensure that the GamePipeline.mll plug-in is loaded.

If Unreal Live Link fails to load properly, make sure that you have Unreal Engine installed to the same machine. Also make sure you are running Maya 2020 or above, and Unreal 5.0 or above.

A custom attribute is missing

If add a new custom attribute to a linked object in Maya, you must re-export it to Unreal and re-import it for the attribute to appear.

Depending on the speed of your machine and the complexity of your file, you may find that the Unreal Live Link Asset Selection window (i.e. the window that appears after you click the plug icon under Link in the Unreal Live Link window) may fail to update in a timely manner. If this happens, try clicking the refresh button. If it times out or fails again, close the Unreal Live Link Asset Selection window and re-open it.
