Here’s my situation:
I created a character in Blender 2.49, with an armature and multiple actions. Exporting to Unity worked fine. I decided to create a gun that has moving parts, and created a second armature for that gun, forgetting that Unity doesn’t like having two armatures in the same file. The export went horribly. So, I got rid of the armature on that gun, creating only one armature in the scene again, the original one that still has actions attached. However, when I save that file, Unity no longer accepts its animations.
Any suggestions?
