@StephanMenzelSAP you’re wording is a bit confusing, can you please clarify whether you’re using the template characters or if you have re-implemented your own characters based on the template characters? I’ve set up and used the template for many multiplayer projects over the years and have never experienced the issue you’re describing.
One idea would be to connect to your server with the original VR 2D pawn from the template and check if the issue is there too, and work your way from there comparing the unmodified template to your character implementation.
