X3DOM TwoSidedMaterial标记不起作用

Question

我尝试在脸部外面给出蓝色，在同一张脸部内部给出绿色。我添加了这个标签。

<TwoSidedMaterial diffuseColor="0 0 1" shininess="0.0" backDiffuseColor="0 1 0" backShininess="0.0" separateBackColor="true" backTransparency="0.0"></TwoSidedMaterial>

diffuseColor =蓝色和backDiffuseColor =绿色但它在两侧（内部和外部）仅显示蓝色。 backDiffuseColor未应用。 This is a refrence link

Answer 1

库中可能存在错误，因为the reference example也显示单个素材（红色）而不是两个（红色和蓝色）：

<x3d>
    <scene>
        <transform rotation='-1 0 0 -1.571' translation='0 13.03 0'>
            <shape>
                <appearance>
                    <TwoSidedMaterial diffuseColor="1 0 0" shininess="0.0" backDiffuseColor="0 0 1" backShininess="0.0" separateBackColor="true" backTransparency="0.0"></TwoSidedMaterial>
                </appearance>
