+# MotionCapHelper
+ maya simple plugin for animator
+
+# main feature:主要功能
+animation curve smooth:平滑动画曲线
+frame align:在参考物体的帧时间k选择物体的帧，并删除其他帧。（对齐帧）
+regular expression:根据正则表达式过滤物体名，并创建（多个）显示层
+animation rebuild:删除范围内外帧，偏移选中物体帧，手动提取关键帧，快速烘焙动画到另一个物体，fk转换ik，钉住世界位置，快速烘焙父子约束效果。
+
+都是非常简单的功能，其中平滑曲线的代码来自https://blog.csdn.net/lulongfei172006/article/details/51493273/

+    example:
+    execfile(r'C:\Users\Chris\Scripts\springMagic.py')
+
+    keep the 'r' in front of your path to avoid IO Error may cause
+
+Tested under Maya 2011 and above, you may need to install Pymel for Maya 2010 or elder build by yourself
+
+Known Issue:
+1.  Error: Syntax error
+    Please check if you run the command in Python mode, you can click "mel" word to toggle between mel and python
+
+2.  # Error: ImportError: No module named pymel.core #
+    That means you are using old version of MAYA and have no Pymel installed, please download and install Pymel follow this page:
+    http://download.autodesk.com/us/maya/2011help/PyMel/install.html
+
+3.  Error: IOError: file <maya console> line 1: 2
+    It mean your path has some error when you run the execfile command, please double check what you typed
