Just re-downloaded to test, works fine for me. Just to be sure, are you using the model in the RahiTuber program or something different like pngtuber+? It likely won't work in other programs.

If that isn't the issue, ensure you've extracted both the "LostTheCat-Portable" image folder and "LostTheCat-Portable.xml" file to the RahiTuber folder on your computer and try opening the .xml in RahiTuber.

The last thing I can think of is the fact that I made the model with the application full-screen on a 1440p monitor, and if your monitor or application window is a different size you may need to make some adjustments to the Canvas Settings if for some reason the model is off-screen by default.
