好吧，我已经使用 JSON 加载器导入了一个多 Material 对象，我正在尝试在运行时访问每种 Material 。
基本上我喜欢修改导入 Material 的颜色。
任何人都可以指导我如何完成它，或者根本不可能吗？
谢谢。

JSON 加载器并添加到场景
var loader = new THREE.JSONLoader();
loader.load( "test.js", function(geometry, materials){
var mesh = new THREE.Mesh( geometry, new THREE.MeshFaceMaterial( materials ) );
scene.add(mesh);
});
最佳答案
如果您使用的是 MultiMaterial(以前称为 MeshFaceMaterial)，您可以像这样访问和更改 Material 颜色:
mesh.material.materials[ 0 ].color.set( 0xff0000 );
mesh.material.materials[ 1 ].color.setRGB( 1, 0, 0 );
研究 THREE.Color() 的文档以查看其他可接受的格式。
