Pymxs, the 3DsMax bindings of Maxscript to Python doesn't come with any stubs. This is an attempt at generating stubs automatically by inspecting running code.

Run generate_pymax_pyi.py in 3DsMax to generate stubs. Tested with 3DsMax 2021 (Python3).

Copy the pymxs.pyi file to a path where you'd usually be able to call import pymxs from.

These Stubs come as they are: I make no promises that they work or cover all your needs.

• Open Directory in VSCode
• Pick the 3Ds Max Python as your interpreter
• Unzip latest MXSPyCom Release into /mxspycom
• Run debug/start_debug.py in Max
• Run Debug configuration Python: Remote Attach
• Run task Execute Script in 3Ds Max on generate_pymax_pyi.py file

• Works in 3Ds Max 2021
• Works with Python 3
• Gets properties of most 3DsMax objects

• Signatures for max script calls (need to go into __new__ constructors of the objects)
• Some properties get skipped as the object they belong to can't be generated without the correct signature
• No #Struct object types
• No properties for regular object types (like Array)
• Not all properties have the right hint (alot will still say None because they need initialization)
• Some Max Scene clean up before, after, during script exectuion (this creates a TON of objects in your Max Scene)
• Check other performance optimizations like turn off viewport rendering as applicable
• Checking if everything is correct, including order of the pyi
• Captialization rules - right now names are read as is, but might be worth enforcing some lowercase or CamelCase rules
• Less hacky code
• Streamline debug/development process
• Encoding definition of pyi file
• Callable for properties/arguments that need it
