Is it possible to semi-automate the process of clearing the lastpose = undefined line in the user defined properties by means of a max script?
Having a lot of objects in a single max file, and having to clear all of them is a pain in the butt for my artists...

Problem solved:
Please run the attached script in 3DS MAX, and it will remove the LastPose = Undefined lines in the user defined properties of each object in the file.
