A big studio might have its own software packing &amp; managing tool and version controlling system.<br />
So they need to be able to update MG-Picker Studio to use the newly-downloaded latest version or roll back to the older version of it.</p><p class="p_Normal" style="text-indent: 0; line-height: 1.80; padding-left: 24px; margin: 0 0 0 24px;"><span class="f_Normal" style="font-family: Arial,'Lucida Sans Unicode','Lucida Grande','Lucida Sans';display:inline-block;width:24px;margin-left:-24px">&#9642;</span><span style="font-weight: bold;">The problem we face:</span><br />
<span style="font-size: 9pt;">Currently, in Maya 2017+, MG-Picker Studio uses Maya's workspace control to autoload itself for a new Maya session.</span><br />
<span style="font-size: 9pt;">Problem is, for the UI script, was hard-coded to the actual path to the loader MEL script, it sources the MEL script and calls a MEL procedure to launch the UI.</span><br />
<span style="font-size: 9pt;">Next time you change to use the new version of MG-Picker Studio, the workspace control config still point to the old MEL path.</span><br />
<span style="font-size: 9pt;">So that means in Maya, you might have the old version already loaded, yet try to load the new version of the tool, which might result in an error.</span></p><p class="p_Normal" style="text-indent: 0; line-height: 1.80; padding-left: 24px; margin: 0 0 0 24px;"><span class="f_Normal" style="font-family: Arial,'Lucida Sans Unicode','Lucida Grande','Lucida Sans';display:inline-block;width:24px;margin-left:-24px">&#9642;</span><span style="font-weight: bold;">How to solve the problem:</span><br />
Starting from MG-Picker Studio v1.83, setup env variable called: &nbsp;MGPICKER_PROGRAM_FILE_DIR , <br />
set its value to the path to <span style="font-style: italic;">MGPicker_Program</span> directory, which contains the loader MEL file called &quot;MGPicker_WrittenByMiguel.mel&quot;.<br />
The test of env is included in the UI script of workspaceControl so will be used prior to the original MEL path. <br />
example in python code to set the environment variable:<br />
<span style="color: #748c43;">import os</span><br />
<span style="color: #748c43;">os.environ[&quot;MGPICKER_PROGRAM_FILE_DIR&quot;] = '/path/to/MGPicker_Program'</span><br />
* For maya 2016 or earlier, the feature is not supported, you need to uninstall and reinstall the tool.</p><p class="p_Normal" style="text-indent: 0; line-height: 1.80; padding-left: 24px; margin: 0 0 0 24px;"><span class="f_Normal" style="font-family: Arial,'Lucida Sans Unicode','Lucida Grande','Lucida Sans';display:inline-block;width:24px;margin-left:-24px">&#9642;</span>The actual MEL code to launch MG-Picker: (python code works alike)</p><div style="text-align: left; line-height: 1.80; padding: 0 0 0 0; margin: 0 0 0 48px;"><table style="border:none; border-spacing:0;">

Starting from MG-Picker Studio v2, the environment variable MGPICKER_USER_CONFIG_DIR is no longer supported to avoid over-complicating things, the user config root dir is always the OS specific user config directory.
