I can export a 3D model with animations in Blender, import it in Godot and use the animations.
But how can I add more animations to the 3D model at a later time?
I can load my .blend file and add more animations. But how can I export them to use them in Godot?
Of course I could export the whole 3D model with all animations again and replace the old one in Godot with it, but this would delete all additional animations I added to the AnimationPlayer (e.g. animations of guns I added in Godot, that were not in Blender).
Is there any way to exchange just animations between Blender and Godot?
(I hope this is not a too Blender specific question for this Godot Q&A)
