Hello 🙂
Which editor and spine-player
version are you using?
You mentioned that you are using consistent premultiplied alpha settings, but are you using straight alpha or premultiplied alpha? If you are using blending modes, they only work if you export your textures as premultiplied.
If you’ve already tried all of that, could you share your export and pack settings?
It would also be helpful if you could share your assets with us in advance at contact@esotericsoftware.com so that, if necessary, we can take a closer look and more easily diagnose the issue.
