So basically i want to know how to export the armor and weapons textures and replace them with my own...all of this in Creation Kit...Iam not intrested in any other programs that can do this.

Ck doesnt edit 3d models. you need a 3d editing program like 3ds max. maya, or blender

You can't do that without using 3rd party programs to open up the master files and extract the models and textures. You would also need an image editor to modify the textures and a 3d application to modify the meshes.

The CK isn't used to create assets, just put them together in the game world.

Ok...thank you very much for ur fast and to the point responses...
Now if i could take another 10 minutes of ur time guys: Can you tell me exactly what programs i need...and how to import retextured weapons in to CK?
Thank in advance.

Have you already made the new textures?
