Whats the right way to insert keyframes for game engines?

I learned how to use blender’s animation tools to create actions for 3d models. What I can’t find is the proper way of inserting keyframes when the model is for exporting into game engines such as godot and unity. Right now I’m inserting the keyframes using ‘available’. Should I be using ‘whole character’?

The more secure way to export animation in a game engine is to bake your animation. 1 key by frame. Using bake action. And selecting visual keying option. In case of skeleton(armature) mainly select the deformation’s bones. And perhaps the root.
Hope it helps. And dont hesitate to ask further informations.

thank you for that information. I now know they should be baked into the exported file.
