I've created an icon to use in my mod, but it shows up blank. However, the picture isn't blank (though it does have a transparent background). Even pulling it up in Windows picture viewer shows the picture.

What did I do wrong?

Here's the picture:

It's probably to loud.

pictures have to be the right size, else they get cropped. Icons = 32x32 px

Yeah, that seems to be the source of it, but it's having issues still >_<. So, when I make the icon *.png file 32x32 pixels, the mod crashes on load-up, saying that it's trying to access the 64x64 loc. But, if I make the image 64x64, it cuts off half the image.



Do I have to make it 33x33?

0.15 will have bigger icon option, but for now you have to stick to the 32x32 px icons.

You might want to delete the cropcache, perhaps that helps. Also: Dont save pngs in anything higher than 16bit colors.

What? That's a terrible suggestion. You absolutely want to save all PNGs with 32 bit color support if you're using them in Factorio or you loose a massive amount of granularity.

Then it was above 32bit, something made problems with mac users

So, icons themselves are 32x32 pixels. What about for group icons? Are those also 32x32?

item/entity icons 32x32
group icons 64x64
tech icons 128x128 (or smaller if you set the matching value to icon_size)

Awesome, thanks Angel!
