    Please take a look at viewtopic.php?f=7&t=2768&p=13484 I think that is what you're looking for. Although you will need to know the name of the slot.

      Thank you!
      You need to say samewhere in manual about "default" skin. I spent many hours to understand how i can work with attachment without skin 😃

      skeleton.findSlot("targetSlot").setAttachment(
   skeletonData.findSkin("default").getAttachment(
      skeleton.findSlotIndex("targetSlot"), "targetAttachment"
   )
);

      Does the same:

      skeleton.setAttachment("targetSlot", "targetAttachment");

      http://esotericsoftware.com/spine-using-runtimes/#Skin

      All attachments that are not in a skin in Spine will appear at runtime in a skin named "default". When a skeleton needs to find an attachment by name, it first looks in its skin. If the attachment is not found, then it looks in the default skin.

      There's a lot to the runtime documentation, things can get lost in all the information. I would love to write higher level documentation.

        Thank you very much and sorry for my inattention!

        I tried to use simple way as you said, but it looks little bit strange for me. Let me explain.
        I have one skin for player. All bones have "skinnable" images except one part. This part just have attached images which i control through code. When i initialize skeleton i call:

        skeleton.setSkin("player");

        In this case calling "skeleton.setAttachment..." gives me:

        Exception in thread "LWJGL Application" java.lang.IllegalArgumentException: Attachment not found: targetImage, for slot: targetSlot
   at com.esotericsoftware.spine.Skeleton.setAttachment(Skeleton.java:257)

        If i remove line "skeleton.setSkin("player");" main images doesn't visible (of course), but presumably skin now is "default", but i still have same problem (Attachment not found). If i call "skeleton.setSkin("default");", main images still invisible (of course), but now calling "skeleton.setAttachment" is works.

        Look at Skeleton#getAttachment(int, String), it tries the skin then the default skin.

        It's only one what worked for me - http://esotericsoftware.com/forum/viewt ... 646#p13646
        I tried namy ways to get attachment, but i'm always have null.
        Anyway - i've got what i need.
        Thank you, guys!

        Oh, i found why setAttachment doesn't work for me - i just forgot to remove old test line from my code 😃

        skeletonData.setDefaultSkin(skeleton.getSkin());
