Hello,
I think it's an issue to not be able to access a dynamic size (x,y,z) from the API.
We can set a size either with dynamics.createBoxBody or dynamics.addCompositeBodyBoxGeometry but we can't obtain the size of a current dynamic created manually with the editor.
So when we adjust manually one or multiples dynamics on an object then want to adapt its scale in game there is nothing letting us adapat the dynamic in API (a sensor follow a scale change but a dynamic doesn't). I can get the offset, apply the scale the set the offset, it works fine but there is nothing for the size, especially when it's not in relation with bounding box.
