Maya优化场景(python)不弹出对话框

没错，该命令的功能就是File -> Optimize Scene Size

使用pymel

import pymel.core as pm

optimize_scene_options = [
    "nurbsSrfOption",
    "nurbsCrvOption",
    "unusedNurbsSrfOption",
    "deformerOption",
    "unusedSkinInfsOption",
    "poseOption",
    "clipOption",
    "expressionOption",
    "groupIDnOption",
    "animationCurveOption",
    "shaderOption",
    "cachedOption",
    "transformOption",
    "displayLayerOption",
    "renderLayerOption",
    "setsOption",
    "partitionOption",
    "locatorOption",
    "ptConOption",
    "pbOption",
    "snapshotOption",
    "unitConversionOption",
    "referencedOption",
    "brushOption",
    "unknownNodesOption",
    "shadingNetworksOption",
]

optimize_scene_options=['displayLayerOption']
pm.mel.scOpt_performOneCleanup(optimize_scene_options)

其中optimize_scene_options可以选择自己想要勾选的优化类型。此时执行会弹出确认对话框

如果要不弹出对话框，可以执行如下命令

import os

os.environ["MAYA_TESTING_CLEANUP"] = "1"

注意：
如果要恢复对话框，不能os.environ["MAYA_TESTING_CLEANUP"] = "0"
必须删掉掉这个环境变量

del os.environ["MAYA_TESTING_CLEANUP"]
