using gizmo on Camera.PERSPECTIVE\_CAMERA is normal, the scaling ratio is fixed. when change Camera.ORTHOGRAPHIC\_CAMERA mode, the scaling will change with mouse wheel ？ How can i fix it? ![20210809155322](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/f/f/ff609f4804c63e5176ad942fa6b427acfa22c417.png) ![2330210809155339](https://us1.discourse-cdn.com/flex024/uploads/babylonjs/original/3X/4/2/42339467e83240fde8f9d9d7c65022a98555d4d4.png) ---

First - it will be wonderful if you can reproduce that on the playground so we can see the problem and try to help. Just a note, @Cedric (who usually answers these types of questions) is OOF at the moment and won’t be able to provide his insights here. ---

This is a bit of a tricky one. I think the issue here is that the gizmo is [usually scaled based on camera distance](https://github.com/BabylonJS/Babylon.js/blob/master/src/Gizmos/gizmo.ts#L214) but in your orthographic camera example, you are not actually moving the camera in space, but instead just changing the viewport dimensions. I thought we could just scale it based on the viewport dimensions, but it doesn’t quite stay the same size: [Orthographic zoom demo | Babylon.js Playground (babylonjs.com)](https://playground.babylonjs.com/#EBPQH9#87) We may have to wait for Cedric to get back for an answer on this one ---

Yes, @DarraghBurke is right. Size is computed base on camera distance. If only the view dimension size change, without moving the camera away, gizmo size will not stay the same. @DarraghBurke To me, the gizmo scale seems ok in the PG. Did you check with some screen capture? ---

Actually, on second look I think you’re right, this solution seems to work. It only appears to change size because it’s changing relative to the alien, but I think it’s an illusion. @DWork does this work for you? ---

Thanks, is works, that’s the best way to do it now 😃
