Convert MSE to MS

mse to ms conversion is most likely related to some kind of export between different scripts from 3ds Max. Considering that both these file types come from 3ds Max it's the obvious and most likely also only option here. Unfortunately, we have not found any specific information if such export or transformation of scrips is doable, or if they are just from different versions of the software.

In any case, if you have issues with the export of mse or ms file types, it would be best to contact 3ds Max support or some community website for help.
