Thanks to work by Gary Tyler MXSPyCom can now be called with the -s flag instead of -f to execute code in a running instance of 3ds Max but suppress any and all error dialogs that may appear. Instead, any error information is printed to the Listener.

A modern version of MXSCOM, to allow for editing & execution of 3ds Max MaxScript and Python files from external code editors.

In 2005 Simon Feltman released the first MXSCOM, a small Visual Basic 6 application that took commands and sent them to Autodesk's
3ds Max's internal COM server. This allowed users to choose their own external code editor for editing MaxScript and to be able to
have their MaxScript code execute in 3ds Max by way of having the code editor utilize MXSCOM to send the file into 3ds Max and have it
executed. Modern versions of Windows can not use Simon Feltman's old MXSCOM.exe program due to it being ActiveX based.

MXSPyCOM is a C# based replacement for MXSCOM. It offers the same functionality as MXSCOM but can run on modern versions of Windows.
It also supports editing of Python files and having them execute in versions of 3ds Max, starting with 3ds Max 2015, that support Python

To Use:

  • Put MXSPyCOM.exe on your harddrive.
  • Put the initialize_COM_server.ms file in %localappdata%\autodesk\3dsmax<Max Version><Country Code>\scripts\startup
    for instance, %localappdata%\autodesk\3dsmax\2017 - 64bit\scripts\startup
  • In your editor of choice add an external tool.
    For instance, in UltraEdit (www.ultraedit.com) go to Advanced \ User Tools \ Configure Tools
    • On the Tool Configuration dialog insert a new command.
    • Set the Menu Item Name to something like, "Execute Script in 3ds Max".
    • Set the command line to the path where MXSPyCOM.exe is located, a -f command switch and "%f", which UltraEdit replaces with the
      filepath of the current document. E.g. C:\Program Files\MXSPyCOM\MXSPyCOM.exe -f "%f"
    • Click OK to add the command.
