Please forgive, for this small offtop, but I want to say a few thoughts for favour the old versions of the programs.
Old games - old soft for them.I think it is normal, and so much! it is GOOD!
Old soft, like 3d max ver. 4->2009 have a lot of a great tutorials and lessons.
His community have a many forums there are can be found a many interesting hints for beginners and for old users. It can be found easily by any search engine.
Else the Old soft is a great useful and it is have a very comfortable interface with a solid stability of working.
Also the old version of the niftools plugs for 3d max are have an optimisation for Morrowind and may work more perfectly than newest version which have the optimisation under Skyrim.
The 3d Max have a great native help system with tutorials, examples and with detailed description of the various options. It necessarily for looking first!
The Best is the enemy for the Good.And not need to afraid for old versions of programs. But on the contrary may should to seek for them! Because in some times, they are have the best optimization for the purposes of modding under Morrowind.
About Blender.The Blender is a very good and powerful program which is being actively developed and gets a lot of new useful options! But in some way it is a weakness for him. (
For example, as has written above honorable mtsr. Pherim, the release of new versions of the plugs for Blender from Niftoolsteam may have a long delay.
All it makes some complicates and slows down the work, especially in the case of a complex model. It's sad, but we will hope for the best!
While it not come to us, will use the old version of the software with the associated plugins.
