Unable to merge mesh vertices with path (result only holes):

Siroquois

Hi, I'm having trouble importing my skeleton into unity.

When I move everything over into Unity, I get the following message

![https://cdn.discordapp.com/attachments/215403845453479936/1367918946816233512/image.png?ex=6816554b&is=681503cb&hm=2dcc79e2cdcaad41413ae45464760421ef634edcb8f882b799fdc01568b834b2&](https://)

and when I try to add the atlas anyway, I get this ![https://cdn.discordapp.com/attachments/215403845453479936/1367918946430353528/image.png?ex=6816554b&is=681503cb&hm=fff32718358553750dd93e84e069cef58a08cc075fdf4fe7fcd18146b877cb40&](https://)

This is the attachment in question

and it does exist in my files

and here it is in the .png created during exporting

I've tried re-meshing the attachment, deleting and re-adding it, but I still seem to get the same error message that only shows up during debug

Admittedly, I'm but a humble artist, and it's my programmer husband who is doing a lot of the unity-side of things, but he also has no idea what this could all possibly mean, so I was wondering if anyone here was able to put the pieces together and tell me what I can do to fix this. Thank you!

It seems like you are encountering issues with importing your Spine skeleton into Unity, specifically related to mesh vertices and atlas textures. Based on the information provided, it could be related to the way the atlas is being packed or how the mesh is being set up. One potential issue could be that the attachment image might be completely transparent, and if the "Ignore blank images" setting is enabled in the Texture Packer, it might be excluded from the atlas. You can try disabling this setting to see if it resolves the issue. Additionally, ensure that all necessary files (.json, .atlas.txt, and .png) are correctly imported into Unity at the same time. If the problem persists, double-check the mesh setup in Spine to ensure that the vertices are correctly configured and not resulting in holes.

Unfortunately, Mr. Robot, none of these things seemed to help 😩 Also, just to get ahead of this: the region is indeed in the .atlas.txt, it's just not being picked up, probably for the same reasons as the holes thing? Highly unclear.

Siroquois Sorry for the delay in responding! I tried to see the image files you attached, but all I got was a message saying “This content is no longer available.” so I couldn't actually see the images. This forum allows you to post images directly, so could you please attach the images instead of the URL?

Siroquois

Oops 😅 here we go.

Two things I should mention:

1). In the debug it references "Underwear/SW/SW - Left Hand - S Uptilt" which is what the attachment was called before I tried renaming it in an attempt at troubleshooting

2). Ultimately I ended up going scorched earth and just deleted all the slots related to hands and started over with them (luckily we're early enough in that it was annoying but not TOO annoying lol). Still, I'm really curious as to what the issue could have been/how it could have been resolved just so I know in the future, and I have a copy of the older version around in case we need more information.

Siroquois Based on the screenshot of the spine.log file you showed us, it appears that you are using Spine 4.3.18-beta. Please note that during the beta period, the editor and runtime versions may not be synchronized, which may prevent files exported from the beta editor from being imported correctly. (For these reasons, we recommend that you do not use beta versions in product development).

If possible, could you send us your skeleton data files via email? That way, we can confirm whether the issue you encountered is related to the beta version or not.: contact@esotericsoftware.com
Please include the URL of this forum thread in the email so we know the context. Then we can take a look at what's wrong.

Siroquois Oops 😅 here we go.

Please note that you've then posted the same error dialog twice in your above posting.

@Siroquois I receive the following error message when importing your skeleton:

For some reason the problematic region includes ".png" in the name, which explains why it's not found: "Missing Regions: Underwear/SW/SW - Left Hand - S Uptilt.png". Could you please check this specific attachment image in Spine? Please also check your Pack Settings during skeleton export, best share a screenshot.

Email Sent!

This was the screenshot I missed (for some reason unity wasn't picking up the atlas upon uploading)

These were the pack settings I was using. During my own troubleshooting, as well as deleting all the hand slots, I had also unchecked "strip whitespace x/y". Dunno if that would have in any way helped.

Siroquois This was the screenshot I missed (for some reason unity wasn't picking up the atlas upon uploading)

This is the same first screenshot again. 🙂

Siroquois I had also unchecked "strip whitespace x/y".

This has nothing to do with it.

Your Pack Settings look good.

As said above, please check the above attachment image Underwear/SW/SW - Left Hand - S Uptilt.png for an additional .png in the name, this ".png" file extension suffix should not be there. You can also send us your problematic Spine project including the images folder containing the attachments, then we can have a look at it as well.
