Hey Perseus, I don't know if you did it purposely or not but you have V2 of IconMaker on the download link.
Yeah, I know, I don't know where the link to V3 is
But it doesn't matter, V2 is exactly the same except you can only make icons for the Spriters Resource, not any other resource
Mighty, you linked the textures resource icons instead of the sprite's.
That's right, V3 works for sprites and models, as well as textures.
