Guys, due to a hardware upgrade i had to reinstall all software for Fallout modding...i found Blender but i cannot find the right version of Python, Pyffi and NIFTOOLS (Nif Scipts or Blender)...which means i cannot make and use custom assets i make...i need help :,(

Ok while I only use blender to certain times like fixing smoothing, I've might've found what you are looking for here in these links.

Blender 2.78a
https://www.blender.org/download/

Niftools for Blender 2.7+
https://github.com/niftools/blender_nif_plugin/releases

I can't find the version of python it needs as it doesn't list it in the requirements :O. Try installing it first without python, It should tell you what python version is needed. Let me know what version is needed and I'll find that.

You can check here for the previous versions of blender

http://download.blender.org/release/

are these compatible to Fallout new Vegas too?

This should be it

Spoiler:

contains everything you need, including the right version of python.

This is the version of Blender I use for New Vegas. It included everything I needed, other than the TRI scripts. http://www.nexusmods.com/oblivion/mods/12248/?

THanks guys you saved me =D
