Original WC3 icons upscaled with Topaz Gigapixel AI

this confirms someone is working on upscaling the classic ones.

This feels like someone made the icons bigger, then smudged them until all visible pixels dissapeared

Just check Darklycan51's Media posts about the HD Classic ones.
Frankly, I wouldn't want an upscale texture version as a Warcraft III remaster. That would suck. They should also improve polygon number/model shapes.

I used this software to work a few months ago. After generating new icons, I still need to modify the details manually
