Just go into Kirby's Ike cap file, and I believe that there's a model of the sword in it.
You were right thanks!
Or you can just use Ike's second sword (the one that he uses for Aether) which is a model that comes in one of his costume files (such as FitIke00.pac/FitIke00.pcs etc)
You were right too thanks!
So now that i got ike's sword model in a mdl0.file i just replace mario's fludd with ike's sword and for the textures:
Pump001 ---> Fit_Ike07 (It has the handle)
PumpEVtank ---> Fit_IkeBlade (Its the blade texture)
Also do i need to rename the model and/or texture?
