HELP With MaxScript MDX Importer/Exporter What Does MSE Extension Associate with it.

I have the impexpmdx.mse file what I'm suppose to do with it? I have no application associated with that extension.

Thanks

Go to the Tools tab(hammer icon). Run MaxScript, choose the script, select it in the dropbox(even if it already shows), then you'll get the import/export functions below.

stick it in your 3dsmax folder, expample: C:\3ds max\plugins\
