当我尝试使用convert_obj_three.py对其进行转换时，出现以下错误。

我已经正确安装了 Python3.*。

可能是什么问题？如何解决？

Answer 1

它给出了语法错误，所以我开始检查语法。发现对python 2. +有效，对3. +无效。然后我刚刚卸载了 python 3.* 它并安装了 2.75。不是它像魅力一样起作用。

Answer 2

你必须有一个OBJ文件吗？如果没有，我建议使用 THREE.js 源代码附带的 Maya to THREE 导出器。它直接导出为 .JS 格式，无需中间步骤。如果您从 GitHub 下载存储库，您可以在 utils/exporters/maya 中找到导出器文件。

您可以在 THREE.js 官方存储库中找到的导出器仅支持静态模型。我创建了一个更新版本，它还支持导出装配和动画模型。我们有一个将更新的导出器与三个主干集成的拉取请求，但如果您想立即获得新的和改进的导出器，您可以从这个存储库获取它：https ://github.com/BlackTowerEntertainment/three.js/tree /maya_animation_exporter。

希望这可以帮助。
