VR Expansion Plugin

I don’t know why it isn’t working for you, there has to be something additional that you haven’t stated.

I tested by literally spawning off of the same node as you, with a default grippableskeletalmeshactor with a generic mesh and attaching it to the waist component and it all worked fine.

You aren’t spawning the hip attachment points client side are you? They are either a default part of the character or spawned server side?

Because the attachment replication wouldn’t work correctly if the clients don’t have the same slots as the server.

You can run some kind of notification code (pint to screen) or breakpoint on tick clientside only to check if the object spawns but doesn’t attach correctly.
