@Lkroner The retina option supports 3x images because of these lines. If something doesn’t work as you expected, you can use onUpdateRule hook to implement the desired behavior. Here is an example - https://github.com/2createStudio/postcss-sprites/blob/master/examples/output-dimensions.md.

Will this retina functionality support 3x images as well? Something like this. I don’t see anything in your documentation about it.
