Yeah I guess just adjust it in your 3D modelling program, or add an extra scene component into the blueprint to offset it.
Ideally the right approach is to override the method the perception system uses to determine if an object is visible. This way you can account for the object’s size and other variables if you need to. There’s an interface set up for this in the code, but as far as I’m aware it’s not currently exposed to blueprints.
