Need advice on a topic

whats the best way to load texture using the mtl format for web and rn environment

The question is unclear.

If you’re trying to load 3d models in .OBJ+.MTL formal to view on the web, you can use THREE.OBJLoader and THREE.MTLLoader,

but the preferred format for web delivery is the GLTF format.

when i load the texture the mapping didnt not come correctly

texture.wrapS = texture.wrapT = THREE.RepeatWrapping
