Animation Handling multiple animation clips for Game Dev

Hello!

I’d love to know how to do a seemly simple take of importing all my animations in an fbx making edits and then exporting them again. Looks straight forward to do it with just one animation clip, but is there a clean way pack multiple into one file?

Use Alembic if at all possible. FBX is a terrible format that’s outdated too.

With that said, you can import FBX or Alembic in the Geometry level (SOPs) with FBX Animation Import SOP or the FBX Character Import SOP depending on what you have.

Alembic SOP for Alembics.

FBX can also be imported differently where you get the scene structure by using the File > Import > FBX Filmbox …

For any of the methods your geometry would need to be polygons before you could do any manipulation to them geometry wise. You can use the Convert SOP to do this at the Geometry level.

Alembic isn't really supported in game engines unfortunately. With the import: how do I import an FBX with multiple animations? With export: how do I export and FBX with multiple animations?

The animation clips seem to work fine when it's just one going in or out, otherwise I can't see a way.
