I get this error when trying to set up live session on UE4, it says the node is from an editor only module. we have tried refollowing the steps from the optitrek system but no success. has anyone ran into this? when we hit play the model disappears, we added a root joint and everything looks good except now we get a warning on the optitrak skeleton node. Could it be the node the software devs for optitrek provided? any help would be appreciated.
