Super Smash Bros. Ultimate Ripping Project

So you know how CrossMod works as a replacement for 3DS Max? Is there any way that can be done for the Splatoon 2 models?

I would have to know the file formats that Splatoon 2 uses before I can help you with that. I don't have access to that game's data files yet, so I can't help you here. If the file formats are the same ones used by Smash Ultimate, you might have a chance to use CrossMod over there.
