I play through the Imperial Legion with every one of my characters, which means that I always end up taking possession of Chrysamere. However since I greatly prefer one handed swords to two handed swords I rarely ever use it. I found a mod on PES while ago that makes Umbra one handed, which gave me the idea to make Chrysamere one handed. I did so in the construction set, but the sword was still huge and it looked absurd when my character was holding it with one hand. I'm still new to the CS, so I don't know how to make it smaller. Is there a mod that turns Chrysamere into a one handed sword (all my searches on PES and the nexus have turned up nothing), and if not is it possible for me to make Chrysamere smaller in the CS?

You can re-size it in the CS—technically—but it will still be full sized when you equip it. To do what you want, it would need to be adjusted in a modeling program, which requires more than simply scaling it.

Actually, if it's just too big but the handle is in the right position, simply scaling down the model might do the trick.

Open the sword's .NIF model in Nifskope, rightclick "NiNode" in the nameslist on the left, select Node->Attach Parent Node.
Should create a new NiNode on top of everything, rightclick it, Transform -> Edit and you can scale it there.

Did that for a one-handed sword I thought was too big and it worked fine, but I couldn't have the scaling apply by using the first NiNode, only way was to create the parent and rescale that. Translating the coordinates of seperate parts of the model seemed to work though.

Thanks. I'll give that a try.

Will this do? http://www.rubberman.me.uk/images/chrysamere.jpg

That is .75 % of the original model.
