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 mode…

This is because gltf models are stored in right handed mode and we reverse them using a parent with a scale set to (1, 1, -1) https://www.babylonjs-playground.com/indexStable.html#0108NG#17 (line 13) On the loading issues, your gltf file is invalid: [image]

Ok so every time I set a parent to a model using gltf, I have to set the scale to (1, 1, -1) right? I actually changed the scaling to (-1, 1, 1) before you suggested it and it seems to work too. And this is only with gltf files? no need to do that with other format like obj or babylon? On the load…

yes only for gltf as babylon file format is already left handed. The gltf loader of 3,3 was less aligned with the spec whereas the 4.0 is spot on. We want to make sure that people are not using bad files :wink: and yeah gltf2 is the way to go
