最近接到个需求：在创建EFX文件时，自动加载动画出的缓存abc文件+相机， 不用手动一个个的载入，还容易出错

ABC文件自动导入到Houndini里

在CGTeamwork里打开对应的镜头，下面的文件列表显示相机和角色文件， 之前特效师手动一个个的参考到houdini文件上去的， 很费劲还容易漏掉，自动化工具需要自动把它们加载到houdin上去。

1. 配置houdini启动器，在参数栏上写入houdini_open_start.py路径， win路径填houdini安装路径，其他的视情况填

CGT启动器参数配置

2. 点击cgteamwork镜头任务右上角的houdini关联， 自动打开houdini软件
   

CGTeamwork调用houdini

3. houndin相机自动载入起始帧，统一的命名。 资产abc自动放到一个组内
   

abc文件载入到houdini  相机文件载入到houdini  特效示意载入到houdini

5. 自定义一个统一的输出节点， 以免输出路径不统一
   

自动创建个输出路径

原理：cgteamwork先调用start, 找到当前的镜头号，给到plugin， plugin算到路径下的abc列表，把列表文件赋给 /obj
houdini_open_start.py
