#1: If you want to increase the height of the player you can either move the NetworkSmoothing component upwards, (it is the root of the tracked devices), or modify the Z value of the CapsuleOffset var on the RootCapsule. I would say to change the world scale but that doesn’t sound like what you are after.
Generally though a remote grip setup is preferred over direct height manipulation from what others have been doing.
#2: Yeah slicing works, it has a bunch of extra logic involved in that slicer though, you have to activate the blade (trigger, it will glow then) and then strike through it with enough force and an impact angle within 15 degress of direct to the surface if I remember correctly).
If it changes to the desk (? lol) sometimes then there might be some BP references being screwy and I’ll need to take a look at it and clean it up. Its been in the template for a long time and I don’t check into it often so its possible that the asset has some broken references from engine upgrades.
