Как импортировать сетчатую анимацию из cinema4d в блендер?

ответ здесь кажется довольно ясным даже при небольшом использовании блендера. XML является недействительным. Это, вероятно, как это должно выглядеть (ниже). Я вижу, где использование открытых тегов вместо закрытых может привести к ошибкам синтаксического анализа. Это удалит ошибки синтаксического анализа, если анимация библиотеки фактически является корневым элементом xml.

<library animation> <animation> data </animation> <animation> data </animation> </library animation> 

В итоге я установил Py4D, так как едва мог найти документацию по КОФЕ.

Мне нужно было экспортировать анимацию точечного уровня и анимацию морфинга в Blender, поэтому я написал небольшой скрипт, который это обрабатывает.
