I am new to 3D modeling and 3D for the web in general. I created my very first model in Blender. Once finished, I tried to export it via ThreeJS. The textures became terrible and some of them didn't show up. Then, I tried it on a model viewer like https://sandbox.babylonjs.com/ and the model displays exactly the same as with ThreeJS. Do you have any advice or suggestions?
My export is in .gltf file format.
