"Could not convert string to float" 将 CSV 导入 Blender 时
"Could not convert string to float" when importing CSV to Blender
我有一个我正在尝试使用的脚本（不是我的），它旨在将 CSV 数据作为网格导入 Blender。
我有两个 CSV 文件，它们是同一模型的两个部分，该脚本可以很好地导入其中一个 CSV 文件，但在我尝试导入第二个时抛出 "ValueError"。
错误可以在这里看到：
据我所知脚本中只有 一个“-1”，我试过更改它，删除它，但没有任何效果，我仍然得到同样的错误.
我也尝试过更改 CVS 文件本身的编码，但这也没有用。
我对脚本编写了解不多，而且我无能为力，我们将不胜感激。
