3D modeling for AR

[Gachelteon]

Are there any standards for creating 3D models for AR? I’ve prepared several 3D models in one file and exported only the selected ones. However, I encountered some validation errors, which I resolved using npm install -g @gltf-transform/cli. After cleaning the file, the model now displays in my AR feature, but it’s not centered—even though I already transformed and centered it in Blender.
