使用 min3d 库将颜色设置为 3d 搅拌机模型

Question

我使用 blender 工具 创建了一个示例 3d blender 模型（蓝色球体）并导出到 .obj。对于 min3D 库，我使用了 sphere_obj 和 sphere_mtl。它工作正常 除了颜色。 它以白色显示。我想我错过了一些东西，但我找不到。我不知道该怎么做，请提供解决方案..

提前致谢

@Override
public void initScene() {
    scene.lights().add(new Light());
    scene.lights().add(new Light());
    Light myLight = new Light();
    myLight.position.setZ(150);
    scene.lights().add(myLight);
    IParser myParser = Parser.createParser(Parser.Type.OBJ, getResources(),
            "com.example.min3dexample:raw/sphere_obj", true);
    myParser.parse();
    faceObject3D = myParser.getParsedObject();
    faceObject3D.position().x = faceObject3D.position().y = faceObject3D
            .position().z = 0;
    // EDIT resize object here with below code
    // faceObject3D.scale().x = faceObject3D.scale().y =
    // faceObject3D.scale().z = 0.009f;
    faceObject3D.colorMaterialEnabled(true);

    scene.addChild(faceObject3D);
