How to convert down a nif file ?

Hey there,

I would like to know if someone could help me to convert down a nif file. Version 20.4.0.7 to v20.0.0.4

Thanks

prob easiest way would be to export the obj or dae from the v20.4.0.7 nif, import it into blender and fix it up if needed, export it back out in a 3ds file and import it into v20.0.0.4, im not sure of any program or tool to do this

EDIT: you might be able to copy the blocks over from one nif to another with ease, but its not always guaranteed
