我需要将网格动画从Cinema4D导入Blender 。
我试图用Collada做到这一点.Collada 1.3进口商似乎没有 做任何事情，Collada 1.4进口商似乎工作，但动画没有得到 进口到Blender。
阅读this post后：
问题解决了！
如果有人来这里看 为了答案，我和大友通过了谈话 电子邮件和他亲切地解释说 问题出在.dae文件中 从C4D输出不正确。
我希望大友不介意我引用 他的电子邮件，我只是不想要其他的 人们浪费我的时间 一个愚蠢的问题。
在文本编辑器中打开.dae 改变：
数据 数据
到此：
数据 数据
两者的fps也必须相同 c4d和搅拌机。
我试过了，但是我收到了一个错误：

The minor version of the file you are using is newer then the plug-in, so errors may occur.

有没有人遇到过这个问题？我在哪里可以找到更新的Collada进口商？ 有关修改导入器的任何提示吗？
注意： Blender 2.5a2 导入collada动画，但坐标系不同，并非所有动画都能通过。例如，当我为一个从0,0,0到100,100,100的框添加动画时， 在x，y，z上旋转它，然后在x，y，z上进行缩放，在Blender中得到：1轴上的平移（x在影院4d中最初是y），旋转很好，缩放比例。
答案 0 :(得分：0)
我最后写了一个剧本。
我几乎找不到可用的C.O.F.F.E.E.文档已经开始安装py4D。
文档非常好，论坛上的支持很棒。

work around
1. store first key for each track curve
2. set the first key value to 1 for the 1st track and 0 for the others
3. store the mesh vertices -> track name verts = []
4. after all track verts are stored, restore the original values
5. write the the curve keys for blender shape keys

它支持ipo键（位置，旋转，缩放）。 点级动画转换为多个形状键。 Morph Tag动画很好地保留了。
