I tried out the automatic icon resizer from Unity, but the result in the Xcode project is unacceptable. It’s like the worst way of scaling down is used, meaning like it just cuts out pixels from random places. Accordingly it looks. I tried “TrueColor”, and tried “GUI Texture” or “Sprite” or “Texture”, but to no avail.
Is there a specific setting to fix that, other than scaling all icons manually? Besides it doesn’t look that bad on Android…
You only have to design your biggest icon on a smart layer and the file will preview it at all the right sizes, then once you’re happy with it a set of actions export it at all the required sizes.
We just released a tool you guys might find useful. It can generate all the icons you need (currently Standalone, iOS and Android out of the box) and it also happens to support App Icon Template directly without any need for export scripts.
I’d be really happy to hear any feedback you might have - especially how to make it even better.
