从 USDZ 文件转换为 glTF 文件 [英] Conversion from USDZ file to glTF file

问题描述

我目前正在尝试在 android 中使用 AR，但我得到了 .usdz 格式的模型.到目前为止，我一直在寻找一种方法来将此文件转换为适用于 android 的文件(.fbx .obj .gltf)，最好是 .gltf.

谁能告诉我这种转换是否有一些支持?

根据我的研究，支持以相反的方式转换文件，即从 .obj .fbx 到 .unsz.

解决方案

现在可以将 USDZ 转换为 glTF...

首先，您需要使用

• 在 Autodesk Maya(预装 USD 插件)中导入 USDC 模型.
• 编辑USDC 模型.
• 使用 Babylon 导出器生成 glTF 格式.

I am currently trying to work with AR in android but I have been given models in .usdz format. So far I have been looking for a way to convert this file into one that works with android (.fbx .obj .gltf), preferably being .gltf.

Can someone tell me if there is some support to this kind of conversion?

From what I have researched there is a support to convert files the other way around, meaning from .obj .fbx to .unsz.

Now USDZ to glTF conversion is possible...

At first, you need to install Autodesk Maya 2022 with USD plug-in.

Then unzip a USDZ zero-compressed archive to get a binary USDC (sometimes ascii USDA) file format and a set of textures. You need to import USDC into Maya. And if you need you can edit those PNG or JPG textures.

Unzipping a USDZ file in macOS...

• In macOS Finder change the suffix of USDZ file to ZIP.
• Uncompress ZIP file using Archive_Utility.app or RAR_Extractor.app.

• In Autodesk Maya (with pre-installed USD plugin) import USDC model.
• Edit USDC model.
• Use Babylon exporter to produce a glTF format.
