3d Object Z(Elevation) position does not update to Preview when assigning 0(Zero) in the event editor. #5684

Is there an existing issue for this?

Describe the bug

When you have a preview open and change the elevation of a 3d object and update, the elevation does not change in the preview if the elevation is set to zero.

Steps to reproduce

Make a 3d object Place it on a project. Set it's elevation to something else but 0 (Like 20). Preview the game. Change the elevation of the object in event editor. Update the game preview. The preview object does not go to zero.

Note: The elevations update works on all other elevations BUT the zero.

GDevelop platform

Additional context

This is the car floating at 20 Elevation. image

This is the car set to 0 elevation and updated. The car is still at 20 elevation instead of 0 that is set. image

Note: The update works on all other Elevations BUT the zero.

Hi @VanCastar, thanks for reporting this bug!

This is due to: https://github.com/4ian/GDevelop/blob/master/Core/GDCore/Project/InitialInstance.cpp#L111

This check was added to avoid writing "z": 0 in every instance (even the 2D ones) thus making the project file heavy.

I guess it will also happen for Rotation X and Rotation Y. I think there is something to do so that the 3D capability stores the Z to fix that. We'll have a look.
