1.设置镜头片段编号、帧率2.添加要录制的对象3.如果勾上，就会创建如下图的关卡序列文件4.如果勾上，创建的关卡序列文件会自动锁定。可点击红框锁图标处解锁5.选择“可拥有”，就不会实例化生成一个LightSource，勾选需要录制的属性6.开始录制7.记得保存你的预设。注意：预设文件不会保存录制设置的帧率数值8.修帧剪去多余关键帧自动对齐：选中关键帧，右键执行“对齐到帧”9.总结TakeRecorder可以将各种动画（动捕、蓝图样条线动画、LiveLink动画）录制到关卡序列文件，以关键帧保存下来，还能后期修帧【遗憾】没找到蓝图能够控制什么时候开始录制，每次都要去剪辑很麻烦

我们在使用pip安装python包时，经常会出现如下错误：ERROR:Couldnotfindaversionthatsatisfiestherequirementxxxx(fromversions:none)ERROR:Nomatchingdistributionfoundforxxxx找了很久终于找到能解决这种报错的方法了。直接选用pip源并且信任它的来源就可以解决这种问题。pipinstall库包名-ihttp://pypi.douban.com/simple/--trusted-hostpypi.douban.com上面使用了豆瓣源，将其换成清华源、阿里源等都适用。清华源：Simple
