Gltf doesnt scale correctly when Vertical Exaggeration is more than 1

CesiumJS

Hi there, I’m having issues with my model lining up with my flight path polyline. Why is the model not rendering correctly when vertical exaggeration is higher than 1?

You can reproduce by going to:

and set:
viewer.scene.verticalExaggeration = 2;

I first thought that this might be related to (or an instance of) Vertical exaggeration is wrong for some tilesets · Issue #12578 · CesiumGS/cesium · GitHub

But … for the MilkTruck example, the scaling looks right for me…?

After seeing 3D model doesnt render correctly with vertical exaggeration > 1 , I tried this out once more. Indeed, when zooming out very far, then it becomes distorted.

This is apparently a result of combining vertical exaggeration with minimumPixelSize.
