Looking to properly texture a model for a weapon mod

[teal sigil]

Hey, how are ya? I was wondering if someone could help me out with a mod I am trying to make for persona 3 reload? I am trying to make a mod for reloaded II, but I am quite new to modding, so I do not know much. I got to a point where I setup the sword model in blender, exported it to UE, and have the texture pack in question, but I have no idea how to properly apply the texture without trial and error. I apologize if this is too much of a newbie question and understand if I need to go learn more first. Any help would be appreciated!

The sword is supposed to look like this lol

Check in blender if the model has multiple UV maps
If so
Delete the ones where the texture does not fit

So I checked if there were multiple UV maps, only found one. I got to a point where I am able to move the parts of the sword around the texture pack and have it reflect on the model as seen here. While I can now move things around, it looks a bit tedious to move each part of the sword this way and have it line up with the texture. Is this the best way to do this with my set up, or is there something else I can do?

If there is only 1 uv map. and it does not match your texture
Then you gotta find the right texture for it

If you don't want to fix it manually

I'm a stupid lol
