autodesk-forge - 如何使用 LMV Toolkit 规范或 Autodesk 材质库材质显示非光照材质 + 纹理？

Question

如果没有查看器对其应用照明效果，我无法成功显示模型+纹理贴图。我正在使用查看器的本地化版本来调查问题，但我欢迎 Autodesk 材料库设置解决方案（如果存在）。

这是我希望如何查看材质的示例，即没有镜面反射，没有反射（忽略此示例在 three.js 中的事实）：https://stemkoski.github.io/Three.js/Texture-Repeat。 html

This is an example of my problem: https://myhub.autodesk360.com/ue29c31db/g/shares/SHabee1QT1a327cf2b7a7879b97973545818?viewState=NoIgbgDAdAjCA0IBGMAsBmATAMwKYBMBaCAQwHYBjQ1fATlUNt13UO1pIwDYZMAOTCVogAukA I have attempted many different "Autodesk Material Library" settings, including ramping up "Self Illumination" however,纹理无法加载和/或光泽仍然存在。可以调整 Materials.json 来解决这个问题吗？这是我的 Materials.json

我建议尝试这种方法。从字面上绕过 LMV 材质（它们都受光照影响）并使用不受光照影响的自定义三种材质。您可能还需要创建自定义着色器。

从这个开始...... https://forge.autodesk.com/cloud_and_mobile/2016/02/custom-transparent-meshes-with-view-data-api.html

让我知道这是否解决了问题，如果没有，我可以进一步深入研究。

最好的，迈克尔
