Most free online tutorials on 3D animations in games teach how to move still objects around in the world. In Minecraft, almost all animations are still objects with transformations applied to them to get them to look as if they are moving.
Not considering AAA titles you normally would see on game consoles and PC, I realized that only complex models have animation, and if they were to be allowed for it, it's usually done with hi-poly meshes. However, simple models, or low-poly meshes tend to be animated by relying on transformations alone.
This gets me thinking. As a beginner who had just started my baby steps toward 3D animation, I have to force myself to overcome my irrational mental denial of not being able to make 3D animations like the ones you see on game consoles. I'm still in the denial stages.
Am I supposed to learn 3D animations from transformations alone, and learn how to use libraries for complex 3D animations some time in the future, when I get more experiences in the field?
