  • Trouble with gif export

    anglais

Hello!
I'm not sure whats happening here:
I have an animation with just transparency for a bunch of slots in loop, when I export it, it doenst seem to be working
BUT
If I animate any bone (and it has to actually be a movement) the gif works
I don't understand, can anyone help?

    This seems to be
    "Movement Requirement: It appears that the GIF export might require some form of movement to function correctly. This could be a bug or a limitation in the current version of Spine you are using. As a workaround, adding a minimal movement to any bone seems to resolve the issue."

    My spine is up to date, I've checked animation selection, and tried diffferent export settings

    I created an animation with the spineboy example project that just faded out his head. GIF export works OK for me. Can you please post or email your project with images so we can see the problem firsthand? contact@esotericsoftware.com

    MWendt Thank you for sending the Spine project. As there were no images attached, I tested it with a green square, but I was able to export it normally even after deleting all the keys except for the slot color key. Here is the result:

    In the editor:

    To test in exactly the same situation you are in, could you send us the images you are actually using, as well as the export settings JSON file? You can save the export settings JSON file by opening the GIF export settings and pressing the Save button in the bottom left corner.

      Thank you!
      I'll send them through email

        MWendt Thank you for sending the image files and the export settings JSON file! I was able to reproduce the issue.
        As a workaround, changing the Background setting from Transparent to Matte should resolve this issue. It also seems that deleting the clipping attachment will also solve the problem.
        I have not yet been able to determine the exact conditions, but it appears that alpha animations with low values cannot be rendered properly when clipping attachments and transparent backgrounds are combined. We will investigate the exact conditions.

          Sorry, what is the clipping attachment? The mask?

            MWendt Yes, in your skeleton, it is named "mask", but this is called a clipping attachment:

            I have successfully reproduced this issue without using your skeleton, and have created an issue ticket here: EsotericSoftware/spine-editor808
            As a result, it seems that this issue can be reproduced even if you are not using clipping attachments.
            It seems that the amount of difference in color is important. For example, if you darken the color of the background image (bt.png) in your skeleton, you will be able to export the animation normally.
            We will investigate to see how we can resolve this issue.

              Very interesting, thank you for the help!
