I have generated a 3d model of my cereal box for testing purposes here. The generated file is in an OBJ format along with a couple pictures in png format that describe the texture and an mtl file. I want to convert said model to GLTF format and tried doing this using this online converter, but it somewhat screws up the textures (I posted a screenshot of this here). Is this a normal thing when converting between OBJ and GLTF? Or is this due to the converter I am using? If so, what is a better way to convert from OBJ to GLTF?
