如何通过Python脚本在Maya中启用Camera Based-Selection工具设置

Hey Jonathan, I’ve been in your shoes—Maya’s official docs don’t always cover every UI toggle’s command line equivalent. Here’s how you can programmatically enable Camera Based-Selection:

Method 1: Directly Set the Persistent Preference #

Maya stores this setting in an optionVar (a persistent preference variable). You can set it directly to 1 (enabled) using Python, which will save the setting even after restarting Maya:

import maya.cmds as cmds

# Enable Camera Based-Selection
cmds.optionVar(intValue=('cameraBasedSelection', 1))

Method 2: Toggle to Guarantee Enabled State #

If you want to ensure the setting is turned on regardless of its current state, you can check the current value first and toggle it if needed—this matches the behavior of clicking the menu item directly:

import maya.cmds as cmds

current_state = cmds.optionVar(query='cameraBasedSelection')
if not current_state:
    # Trigger the menu toggle action to enable
    cmds.toggleCameraBasedSelection()

Quick Notes: #

• The optionVar method updates the underlying preference, so your script doesn’t need to rely on the UI being loaded.
• toggleCameraBasedSelection() will immediately update the menu checkbox in Maya’s UI, which is useful if you want visual feedback alongside the setting change.
