Nice write up. I tried doing Cloud's model from Mobius and it showed up invisible even though it said it was a success, so I tried a different version of the model that I converted to FBX with blender and resaved the textures from .dds and .tga formats to .png, since .dds and .tga aren't supported by the tool, and then when I built that it worked and said it was a success, but when I go load a save file the game just crashes, so I don't know what's going on with that.
So then I tried doing Sora's KH2 model that I also converted to FBX with blender, and that loaded in just fine but the axis coordinations were all off so he appeared much further back than where the player model is supposed to be, and I still aren't too sure how to do the bone setup yet so he was still just in a T pose, I'd just have to reset his XYZ coordinates in blender to be centered between his feet to fix that though. Though this is the first time I've ever used blender so I'm still getting used to how things work in that too.
Edit: Ok I tried resetting his XYZ coordinates and that worked, but he's still really big so I need to change the scaling. Btw I'm playing on the lowest settings because I have a toaster.
