"multiple sprites" → change resolution?

Hi,

I have a PNG with multiple individual pieces and am using the “multiple” setting and sprite editor to take them apart:

So far, so good; Now I decided that I wanted my sprites in higher resolution, so I exported them again from sketch using the quadruple resolution.

The problem I have now is that the settings in the sprite editor are messed up.

Will I have to create them all over again or is there a way to uniformly scale all these sprite “slices” to match the new texture size?

As far as I understood you’ve sliced them 64x64. Now you’ve scaled them x4. So now they should be 256x256.

Press “Slice” button on top-left corner of your Sprite Editor. Now you have 3 options, either automatic + sett your settings and press slice OR yourself (grid) then set pixel size to 256x256 + sett other settings and press slice OR if you’re not happy with that you can manually size all of them by selecting each one and resizing and positioning properly, though I can see no reason why would you do that.
