Hey everyone,

I’m looking for a way to set a simple shape to my custom PhysicsVolume class created in C++. When I’m spawning this custom PhysicsVolume class, it doesn’t have any shape set, I thought it would be as in the editor, a basic box of 200x200x200. This is what I want, if anyone can help, would be appreciated, thanks a lot.

Up, I really need an answer on this please, I need to spawn a PhysicsVolume for every character I have, and I can’t even create a blueprint from PhysicsVolume, only a C++ class so I can’t bypass the issue I’m having with editing a blueprint with the correct shape and spawn it at runtime.
