A weird question about textures

My first ever post so please forgive me if I’m doing it in the wrong forum.

With the creators permission, I’ve extracted some models and textures from the game files, but noticed something strange with a few of the textures. When they’re on my desktop, they’re mostly transparent, blank spaces with nothing in them. Even placing them in photoshop and trying to look at the RGB channels doesn’t show anything, but when imported to Unity you can see everything.
I’ve added a couple of images to illustrate when I mean. The first is the texture when I open it with the photo viewer in windows. The second is how the textures looks in the Unity preview.
Can someone help explain this discrepancy? I’d love to be able to view the texture normally.

Which format your textures are?

They’re all PNG files

Looks interesting… Can you share you source file to inspect?

I think you most likely just have transparency in your images. But it would be easiest to check the issue if you can share some original texture.

sure, you can get it from https://i.imgur.com/zkD3KDi.png

I’m pretty sure that’s the case as well, so check the imgur link to see the texture as-is.

well that was a new thing for me,

(so in unity it shows that rest of the image, if transparency is disabled)

Wow, that was actually it, thank you so much!
