Oh okay. I thought maybe you had already. I tried it last night to see if UE 5.3 would pick anything up but nothing shows up in Live Link. Today I tried it in 5.5 and was able to add the Xsens source but as soon as I hit stream on your UI it crashes UE.
This is using the release from March. Not sure if the 1:1 would change anything. I'm not seeing the ability to download that update on my end.
