Another problem worth talking about:
If you are going to use Scene Capture 2d, be prepared that all Skeletal Mesh attached to the Motion Controller will lag behind the Motion Controller itself. This will happen if you just put active Scene Capture 2d anywhere in the world. It doesn’t matter where or how.
To fix this just go to the Motion Controller settings in the “Motion Controller” tab and set “Disable Low Latency Update” to “True”.
