I made a sprite. I put this sprite to Spriter for skeletal animation. It was a simple object which mostly merely rotated and which went up occasionally. I tested it, refined it here and there: it all looked good.
The animation was exported as a .PNG file set. When this file set was imported into Fusion and set to play looped, it did not show all expected movement: rotation took place, but the going up and down did not.
When inspecting the .PNG file set, it all looked good. Hot spots for export and import were also just right. Whether I imported it with the crop option or without did not make a difference.
I am by trade no graphic artist and no animator, but I am getting by and learning. So I could use some help.
So how can it be fixed?
