Issues with jagged borders in three.js while working with gltf documents

Seeking assistance for resolving an issue with a bug.

https://i.sstatic.net/F1fov.png

The problem is seen in the gltf import of a "sheep-like" object, exported by blockbench. Adjusting the scale does not solve the bugged edges that persist no matter what scale is applied.

const loader = new GLTFLoader();

  loader.load( './sheep.gltf', function ( gltf ) {

    var gltfO = gltf.scene;
    //gltfO.scale.set(0.05, 0.05, 0.05);
    gltfO.position.set(0,-sz/2,0);
    scene.add( gltfO );

  }, undefined, function ( error ) {

    console.error( error );

  } );
  

Answer №1

It seems that the problem lies in UV Mapping. I've managed to discover a workaround using Blockbench. Instead of only painting within the rectangle on the UV, it's necessary to also paint the border OUTSIDE the rectangle. While not a perfect solution, it serves as a temporary fix. It may not be effective for textures with multiple colors, but it does the job in this particular scenario.
