Hi I would like to control the max speed of a pawn using this parameter under physics
is there a BP node for this
hi Dino 
If you are looking to control your physics pawn’s max speed, I’d look elsewhere (default physics volume friction in project settings, terminal velocity etc… maybe set linear velocity using a clamp). Unless there is a solid need for it, consider using the usual Pawn and Character… With so much power and control… physics in UE4 can get a bit complex… see my other post today for a bit more info
I haven’t looked into it a lot but depenetration velocity is specifically related to the speed at which actors collide and pass through each other.
right click in your blueprint > uncheck context sensitive > type “depenetration” > pick the one you need
I think the target will be your character movement component, not sure though
i,m just add impulse to move the player it is a normal pawm
