Hello, we notice that something was wrong when we import our model but we didn’t find out what until we used that earth: https://www.babylonjs-playground.com/indexStable.html#0108NG#16
When you set a parent to meshes imported from a model, the meshes become reversed. Hard to see with geometric models but very well visible with that earth. And without a parent the meshes stays correct.
Plus I notice that with the latest babylonjs version, the model can’t be loaded correctly, there is only one mesh in the callback instead of two.
