Maya FBX导出导入

问题描述：

Maya 导出导入 FBX，设置 FBX 的导入和导出设置

解决方案：

获取FBX设置

python 复制代码

def getFBXSettings():
    """ get current user settings for FBX export and store them """
    mel.eval('FBXPushSettings;')


def setFBXSettings():
    """ set user-defined FBX settings back after export """
    mel.eval('FBXPopSettings;')

导出 FBX

python 复制代码
