Using modo model editer help

[assassin1]

I am using modo model editer for some 3d work but when i export the obj back into a nif it is not the same it is missing some blocks!

so then i export it into the game and i got missing meshes! (because of the missing blocks)

so i would like to know is there any nif import and export script for modo,They have one for blender!

I think i might jest go mad if this is not fixed :wallbash:

 

 

 

so basicly i would like to know how to import my mesh into a "Nitrishape" already in that nif file.

but when i try to do that i can not put it in! it is driving my mad if this is not resolved i may have wasted hours of work!
