So, I've downloaded http://www.fallout3nexus.com/downloads/file.php?id=3907 mod beacause I like the look of the Junk Metal Knife. The problem is, I think it's too big. It's about the size of a machete, so basically like a small sword, but I want it to be more like a knife. About the size of a combat knife would be perfect I think. What I want to do is resize the knife and make it smaller. Nothing else. However, I can picture a problem wen you just resize it, and that is that for example the handle and blade would be too thin. But I don't know how to do it, I've just imagined it being like resizing a picture
I don't have any experiences in any 3D-model program, and barely know my way around GECK. I have only used GECK once when I altered the stats of a weapon.
I was wondering if anyone could tell me how to do it, and which programs to use etc. If anyone would be kind to do it for me, that would be awesome, but just help is fine because it would be nice to know how to do these things so I don't have to ask for help the next time I want something done.
Since I lack experience, I'm afraid you'd have to tell me every basic thing, like how to get the altered knife into the game and stuff like that. Thanks.

If you can open the file up in the GECK, then in the render window, hold 'S' and mouse-wheel the object to desired size.

Changing the scale of a ref only works on that one ref, not on all the instances of the knife in the game. To change its scale permanently, you would have to edit the scale in Nifskope. Though this won't change the collision size of the knife, and it might not fit properly in the wielder's hand. For that you would need a 3D modeling program or be a super expert and have lots of time to do it with Nifskope.

nah. it would take 5mins in nifskope maximum. using a 3d prog would take longer just to load the program and import the object, then you'll have to go through all the export set up and post export set.

do it in nifskope, its just basics. it'll take me as long to post this message as it would do to all this
rightclick the nitristrip>transform>edit. edit scale. 0 xyz is where the weapon bone attaches to the knife in game. this is the point in the middle of the hand. so prehaps move the knife again by editing the translation. then rightclick the nitristrip>transform>apply.

delete the collision shape. rightclick it, block>remove branch. leave this nif open...

open the baton.nif weapon nif. steal the capsule shape collision from this.
rename the root node to match your knife nif, so you don't get the failed to map parent error. or just unhook it from being the collision object of scene root node

rightclick the collision block> block>copy branch

back to the knife nif
rightclick the scene root>block> paste branch

hook it up as the collision object of the scene root.

fiddle with size of capsule to suit.

save

Hahahah - You know Ghogiel, 5 minutes for you is 3 hours for me... :brokencomputer:

Okay, thanks guys. I'm gonna try it out.
