I don't know, maybe is a misconnection between the AssetStudio and the Asset, but I am sure some of these assets are encoded and i don't know how to decode them either.
I'm having an issue with using Asset Studio to rip files from Fallout Shelter. I did it before earlier this year, but since the game's latest update, wjhen I open the .obb file in Asset Studio and try to view the Texture2D files, they variably display no preview image (the bottom message window says its an unsupported image type), I get an error pop-up, or the file displays as a static rainbow of pixels. In all three cases exporting doesn't work, the first two can't export and the latter exports the pixel static.
Anyone have an idea what's going on?
Is there a way to speed up the files extraction from the assets? I wanted to extract sprites from a game and some of them took a VERY long time, so overall it ended up taking about 5 hours to extract 5 GB of images.
Am I doing something wrong?
P.S. I've used zhangjiequan's AssetStudio since it seems to be more recent.
