Material/visibility animation exporting (Pokémon SuMo)

[Metalcape]

Is SPICA capable of exporting material and visibility animations? I am trying to export as .dae and import into Unity, the model comes with materials already assigned and Unity automatically recognizes the textures (except for occlusion/normals) and animations play correctly, but material/visibility animations are not there.

For example if I'm exporting something like Blaziken, everything plays correctly in SPICA but after export the fire on its wrists becomes black and white and it's always visible, instead of disappearing accordingly with animations. Same goes for the eyes which are animated through texture offset, that is also lost after exporting.

I was wondering if it's a compatibility issue between programs (and hopefully in that case I can look into a solution) or if it's just not possible to export those animations because of file format limitations.
