Three.js 该材料的克隆工作不正常

改变新材料的参数会对旧材料产生影响

var material = new THREE.MeshLambertMaterial({
    map: Texture,
    side: THREE.DoubleSide
});

    material.map.repeat.set(3,3);
    material.map.offset.set(0.1,0);    

var geometry = new THREE.PlaneGeometry(100, 100, 1, 1);    
var mesh = new THREE.Mesh(geometry, material);

mesh.position.set(-70, 0, 0);
scene.add(mesh);

var material2 = material.clone();

    material2.map.repeat.set(2,2);
    material2.map.offset.set(0.5,0);    

var geometry = new THREE.PlaneGeometry(100, 100, 1, 1);    
var mesh = new THREE.Mesh(geometry, material2);

mesh.position.set(70, 0, 0);
scene.add(mesh);

也许您需要用几何语言设置“重复”和“偏移”纹理？

材质。克隆制作一个浅拷贝，因此您最终会得到两个具有相同贴图的不同材质。如果要在纹理上设置不同的值，还需要克隆纹理

var material2 = material.clone();
material2.map = material2.map.clone();
material2.map.repeat.set(2,2);
material2.map.offset.set(0.5,0); 
material2.map.needsUpdate = true;
