Question

我想为我的伪造查看器设置一个黑色背景，但是我不知道该怎么做...我想在全息齿轮上运行它来进行一些测试。

我正在尝试此查看器

        path: null, tonemap: 0, E_bias: 0, directLightColor: [1.0, 0.84, 0.67], ambientColor: [0.8 * 0.25, 0.9 * 0.25, 1.0 * 0.25], lightMultiplier: 1.0, bgColorGradient: bg["Fusion Grey"], darkerFade: false, rotation: 0.0 }, //Fusion Environments which require extra lights

我在viewer3D.js上发现了这个，但是当我全黑时，什么也没发生。

使用viewer.setBackgroundColor(0,0,0,0,0,0)，请确保在初始化查看器后调用它。
