Distortion, color replacement on glb (gltf) models. Blue changes to green, and yellow changes to orange.
v106 three.js
v97 GLTFLoader.js
Can you make a jsfiddle that reproduces your issue or show how you’re setting up your renderer? Are you setting renderer.outputEncoding to sRGBEncoding?
// IMPORT THE GLTF MODEL:
// from https://threejs.org/examples/#webgl_loader_gltf
const gltfLoader = new THREE.GLTFLoader();
gltfLoader.load(SETTINGS.gltfModelURL, function (gltf) {
gltf.scene.traverse(function (child) {
if (child.isMesh) {
child.material.envMap = envMap;
}
});
gltf.scene.frustumCulled = false;
// center and scale the object:
const bbox = new THREE.Box3().expandByObject(gltf.scene);
// center the model:
const centerBBox = bbox.getCenter(new THREE.Vector3());
gltf.scene.position.add(centerBBox.multiplyScalar(-1));
gltf.scene.position.add(new THREE.Vector3(0, SETTINGS.offsetYZ[0], SETTINGS.offsetYZ[1]));
// scale the model according to its width:
const sizeX = bbox.getSize(new THREE.Vector3()).x;
gltf.scene.scale.multiplyScalar(SETTINGS.scale / sizeX);
// dispatch the model:
threeStuffs.faceObject.add(gltf.scene);
},
function (xhr) {
if (xhr.loaded == xhr.total) {
console.log((xhr.loaded / xhr.total * 100) + ' % loaded');
document.body.classList.remove('loading');
threeStuffs.faceObject.add(PARTICLESOBJ3D);
}
}, function (e) {
console.error(e);
}); //end gltfLoader.load callback
Unfortunately this doesn’t help a whole lot – it’s not runnable on it’s own and it’s missing a lot of important code specifically the renderer initialization. I would check the outputEncoding of the renderer to make sure it’s set to sRGBEncoding. Can you also test to see if the model looks correct in this viewer:
Yes, displayed correctly.

The visual appearance of the material depends on the lighting conditions e.g. the used environment map. Just for testing, please do not set an environment map but add a simple ambient and directional light to your scene? How does this setup affect rendering?
var ambientLight = new THREE.AmbientLight( 0xffffff, 0.4 );
scene.add( ambientLight );
var dirLight = new THREE.DirectionalLight( 0xffffff, 0.8 );
scene.add( dirLight );
