=============this is just some background stories about this particular incident============ Hey I am new to modding and blendering A while ago I find a costume mod "Taokaka" and notice that the author of it is abandoning that mod. I like that mod quite a lot and so I thought, "maybe, just maybe I could be the one finishing it" So I started making my new parts, the tail of that character, claws, and some other missing stuffs. ========END of story======== For the tail I used ANB's furry tail resource. I have the item in the game already, I made some black fur for the tail, everything in nifscope and blender looks fine. But in game when I put that tail on, there is nothing, nothing at all for my character. I also tried to make a more revealing+double-melon version for Night Knight by NKI I imported the whole thing in Blender, deleted the old-meat and replaced it with double-melon upperbody. I kept all the bones and deleted the extra bones from the imported DM body I moved stuff around and re-sized the chest plate I replace the original file with this and check the oblivion thing in the save window I changed the mesh in blender and nothing else It is not showing at all game Something I noticed, if I am just deleting stuff it will work just find. If I happen to move stuff around or resize stuff, the nif file is not gonna work in Oblivion What is happening to me? (by the way, I hope this isn't a FAQ by newbies)
