Duplicate mesh & high quality export

ofir corcos

Hi guys,
a couple of questions:

I want to duplicate a mesh with the image&bones that bind to it, so I can flip it and use it to the second eye. Is it possible? because when I try to do it only let me see one mesh at a time.
Is it possible to export a png sequence in 300 dpi? If so, how? (I need to take the animation into photoshop and then AF, if it's matter)

Thanks in advance!

Hello Ofir!

I suggest parenting all the meshes and bones that influence these meshes under a bone, then duplicating this bone. This will make sure that the copy of the mesh follows the copy of the bones instead of the original bones. If you want to flip the eye, I suggest to flip this main parent bone as well instead of each element.
you can't specify dpi, but that's something that unless you are going to print, doesn't matter. Instead, you want to be able to specify the pixel size of the image, and this is something that Spine allows you to do when specifying the Size setting on export: Export - Spine User Guide: PNG

Thank you Erikari!
It worked🙂

About the export, the animation will appear in the end on a wide HD, and maybe 2k. so I'm a bit skeptical about the 72 dpi thing. So if I got it right, I can export the png's in a big image format (let say 3840X2160) and then the dpi won't matter?

Yes, you are right about that. As Erikari said, the DPI don't matter - it can be a bit confusing, an article that explains the misconceptions a bit can be found here. I would not be so picky about dpi vs ppi as the author however.

In short: if you have the same image data (e.g. 3840X2160) it will not make things better or worse if you put a different dpi/ppi label on it without changing the content.

I feel there might be a little confusion on DPI here, as they are useful with printed media (dots per inch) but futile when taking into account digital media: If you are exporting an animated png sequence, I assume you're not going to print it. Standard screen dpi is 72, and animation atlases/sequences are made to be seen on a screen and not printed, but it really doesn't matter, as what really counts is the pixel size of your image.
You can find a nice and detailed explanation here:

If it's really important for you to have 300 DPI in the exports, you can do like the guy in the video I linked above at around 4:14 and re-save the exported sequence, you can also set a photoshop action and therefore batch your files to set the DPI at 300, but this is not going to change in any way the substance of the exported pngs, so don't worry (:

In general, just remember that Spine is already using an optimized compression algorithm to get the best images on screen with the smallest possible file size, and the same can't be guaranteed if you re-save images with photoshop.
