bitcat I'm sorry to hear you're having trouble. Mario, who is in charge of spine-godot, is currently on sick leave and may not be able to check in right away, but we would appreciate it if you could provide us with a minimal godot project that can reproduce this issue so that we can smoothly investigate this issue when he returns: 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.

bitcat Glad to hear the problem has been resolved! Thank you for sharing about the solution. That information may be helpful to future spine-godot users who encounter similar problems.
