从Cinema4D在3D动画搅拌机 [英] 3d animation from cinema4d to blender
本文介绍了从Cinema4D在3D动画搅拌机的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我需要导入从Cinema4D在网格动画进入搅拌机
我想这样做使用Collada.The Collada的1.3进口商似乎不
做任何事情，为Collada 1.4进口商似乎工作，但动画没有得到
导入搅拌机。
I tried to do that using Collada.The Collada 1.3 importer doesn't seem to do anything, the Collada 1.4 importer seems to work, but the animation didn't get imported into Blender.
问题解决了！
在任何情况下，在来这里寻找
答案，我通过采访了大友
电子邮件和他亲切的解释
问题就出在.dae文件是
从C4D正确出口。
In case anyone comes in here looking for the answer, I spoke to Otomo via email and he kindly explained that the problem lies in the .dae file being exported incorrectly from C4D.
我希望大友不介意我引用
他的电子邮件，我只是不希望其他
人们浪费我这样做的时候
一个愚蠢的问题。
I hope Otomo doesn't mind me quoting his email, I just don't want other people to waste the time I did on such a stupid problem.
在文本编辑器打开了.dae和
变化：
Open up the .dae in a text editor and change:
数据
数据
data data
这样：
数据
数据
data data
的fps的也必须在两个相同的
C4D和搅拌机。
The fps must also be the same in both c4d and blender.
我试过，但我得到一个错误：
I tried that, but I get an error:
FEEDBACK: Illusoft Collada 1.4 Plugin v0.3.162 started
The minor version of the file you are using is newer then the plug-in, so errors may occur.

有没有人碰到这个问题？我在哪里可以找到一个新的Collada进口商？
关于修改进口商任何提示吗？
Has anyone come across this issue ? Where can I find a newer Collada importer ? Any hints on modifying the importer ?
请注意：
搅拌机2.5a2 进口COLLADA动画，但坐标系是不同的，不是所有的动画使它通过。例如，当我动画一箱从0,0,0至100,100,100，
在X，Y，Z旋转和缩放它在X，Y，Z，在搅拌机我得到：翻译1轴（X最初为y在CINEMA 4D），轮换是好的，规模忽略
Note: Blender 2.5a2 imports collada animations, but the coordinate system is different and not all animation makes it through. For example, when I animate a box from 0,0,0 to 100,100,100, rotate it on x,y,z and scale it on x,y,z, in Blender I get: translation on 1 axis(x which originally is y in cinema 4d), rotation is fine, scale is ignored.
推荐答案
我最后写一个脚本。
我几乎没有发现可用C.O.F.F.E.E.文档，以便继续和安装 py4D 。
I barely found usable C.O.F.F.E.E. documentation so went ahead and installed py4D.
该文档是pretty好，在论坛上的支持是惊人的。
The documentation is pretty good and the support on the forum is amazing.

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

它支持的IPO键（位置，旋转，缩放）。
点级别动画被转换为多形键。
变形标记动画preserves很好。
It supports ipo keys(position,rotation,scale). Point Level Animation gets converted to multiple shape keys. Morph Tag animation preserves nicely.
