Okay solved it thx to the nexus-chat just had to unpack the skyrim meshes.bsa file for that.. thx anyway

Hello all.. since its my first time here in forum, im sorry if its in the wrong place.. first i already searched for my problem (i didnt go through all threads but most) and didnt find my problem. I also googled a bit but didnt find what i was looking for. Now to my problem...right now im watching this video: http://www.youtube.com/watch?v=o7yCk1nsk88 and thats what i pretty much want to do, but what he is showing at around 03:18 i dont have these.. he is showing these stuff as .nif files but i just have them as .tri files and i cant open these in outfit studio. Now my question..how do i get these as .nif files.. i really hope someone can help me with this issue, i just wanted to get tbbp on vanilla outfits and now i have way more to do than this. Yes i know there is a mod out for this, but i wanted to do it myself, so i can maybe do some conversions from standalone outfit-mods which do not have tbbp supported to well tbbp or something else.. But as i said thats not possible as long as i have tri files and not nif files :/ Well even if u cant help me with that, thx for reading..if u can help im begging u help me :/
