Custom Gizmos in the Editor

Is there a way to add custom gizmos to an object that show up in the editor? I’m trying to implement my own simple Physics system and each object has a BoundingBox. Is there a way to draw a wire-frame rectangle in the editor screen that represents the BoundingBox in a script?

Thank you.

Currently Xenko Game Studio does not support any form customization. Unless you are willing to pay for the higher tiers. Pro Plus and above does give you access to the source of Game Studio. See Get Xenko.

But we may get extensibility at some point. As shown on the Road Map.
