一 需求
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
二 过程/效果
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。
- 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
- 点击cgteamwork镜头任务右上角的houdini关联, 自动打开houdini软件
- 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
- 自定义一个统一的输出节点, 以免输出路径不统一
三 代码
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
import os,glob

G_NukePlugin_Path = os.path.dirname( sys.argv[0] )
sys.path.append( G_NukePlugin_Path )
