I want to overlay/switch on&off a texture from a GLTF model, but can't find how or if is it possible. I was able to load it perfectly, but when I try to reload or overlay the texture nothing happens or I get some errors. The last thing I tried don't give me any errors, but the model keeps the original texture. I also tried to unload the model and reload again with other texture, no success either.
I'm using the standard THREE.GLTFLoader example from three.js docs, just changed the 3d loaded model and added a function to do this changes after some time. I'm probabily confusing everything, if you can help I will appreciate, thanks in advance.
Accessed links that does not help me: ThreeJS: Remove object from scene; three.js Switching objects on click; How do I change the texture of a GLTF model dynamically?; Change texture of loaded .obj in three.js at runtime; Import another Texture at runtime within THREE.JS and GLTF

UPDATE1 (removed the newTexture function and edited the model's loader):
// model
var loader = new THREE.GLTFLoader();
loader.load( 'models/testeFinal2-1/testeFinal2-1.gltf', function ( gltf ) {
globalObject = gltf.scene;
gltf.scene.traverse( function ( child ) {
if ( child.isMesh ) {
child.material.envMap = envMap;
setTimeout(function () {
child.material.map.image.currentSrc = "/models/testeFinal2-1/2/finalTest2_ORTO2.jpg";
child.material.map.image.src = "/models/testeFinal2-1/2/finalTest2_ORTO2.jpg";
}, 5000);
}
} );
scene.add( gltf.scene );
} );
child.isMesh === true, try logging the value ofchild.material. Are any of the materials an array, like[ Material, Material ]? If you have a multi-material mesh you'll need to add the envMap to each individually. - Don McCurdy.srcwill have no effect, you'll need to use aTextureLoaderinstance here, (3) hm ok that's not the issue then. Maybe I'm confused — is changing.mapnot working,.envMap, or both? You can reassign.mapwith something like:var texLoader = new THREE.TextureLoader(); var texture = texLoader.load('foo.png'); child.material.map = texture. - Don McCurdy.map) texture, be sure to settexture.flipY=false. - Don McCurdy
