I have tested your FBX model and the animation exports ok (as far as I can tell). You need to enable it in the “Transformations” tab, “Export Animations”. I would recommend also to tick the “export matrices” box, unless you can handle the original quaternions.
By the way, we discontinued PVRGeoPOD development a couple of years back, so our support will be very limited.
The PVRGeoPOD is still available for download. It is just that we do not maintain this tool any longer. We have plans to make the full source code open-source, but it is taking longer than expected.
By the way, if you are using Blender, the whole interface is editable Python so you can update if you require it.
After you exported the animation to POD were you able to playback the animation inside the PVRShaman?
I just followed your steps and after importing the POD into Shaman and pressing play I do not see the animation.
I am using 21.2@6162260 which is the one you can find in our Download page in the Legacy section. There is no real alternative unless you move to use a different format like glTF which has a very wide support.
The PVRGeoPOD python interface for Blender is editable and that will allow you to do fixes or extensions easily.
