Well i wanted to combine some parts of some armors to another one .I did that in NIFscope .Manage to find a tutorial .DId what the Tutorial sayd but the game keeps crushing .I do the Copy block paste block and stuff then optimize and save as .Anyone able to give me some tips ?

Can you link to the tutorial? I've never modded an armor in Nifskope before, but a source would be helpful to others giving advice in case the tutorial contains incorrect or outdated information.

Here is the source where i found it http://forums.nexusmods.com/index.php?/topic/242546-how-to-customise-an-outfit-in-nifskope-beginners-tutorial/ also i found some easier tutorial but i cant find the page .Well u just go copy branch and paste branch and then optimize and simplify thishape or something like that or combine properties .Sorry im not really good at explaining things .

You're much better off doing any sort of in-depth mesh work in Blender than Nifskope. The NS method does work if done properly - but it doesn't allow you to adjust/edit the mesh to nearly the same degree.

I agree 1,000% with tesvixen. Nifskope mesh editing is a nightmare. Blender is another program to learn, but it's free, easy, and allows you to actually create quality things just as you want them. It will allow you to do what you want where nifskope is buggy and convoluted.

And I, in turn, agree completely with Dragbody. Many of my most modding moments came from 'Copy Branch/Paste Branch/Copy/Paste Over' issues in Nifskope.

So I try to do as much as absolutely possible in Blender.

Well i manage to copy paste it ...Blender is too much for my brain to handle at the moment .But i will give it a try .It will took me some time .Thx 4 the info.

Also what kind of blender do i need ,and what plugins and other stuff do i need if i want to mod the meshes with blender ?
