Sekiro: Shadows Die Twice making mod problem

[Alvahkiin]

Hello there,

 

I have been doing a mod for Sekiro: Shadows Die Twice, just changing Ookamis' model to a Waluigi.

The thing is that everything goes well, until I try to rescale the model in the FLVER editor. The tutorial I have been using to guide myself is this,

, in which at the minute 4:18, he or she just imports the model, rotates it, and when I use the rescale measures that he or she uses, just makes it bigger, not smaller as happens in the video.

Can please anybody help me?

Fixed, just rescaled it in Blender or Maya.
