# 调用
|
||
使用Rokoko与BetterFbx插件。这里因为需要规避Rokoko插件名带有“-”的问题，所以还需要安装Importlib库
|
||
```python
|
||
import bpy
|
||
import os
|
||
import sys
|
||
import importlib
|
||
rokoko = importlib.import_module("rokoko-studio-live-blender-master")
|
||
from better_fbx import *
|
||
|
||
|
||
# 启动命令参数
|
||
'''
|
||
# blender --background test.blend --python mytest.py -- example args 123
|
||
cd /d D:/Program Files/Blender Foundation/Blender 3.3/

|
||
|
||
# Blender后台启动并且执行Python
|

|

# Python CMD 交互方式
