Animation support with of ofxAssimpModelLoader

I am using ofxAssimpModelLoader to attempt to load in an animated model. I can get the model loading and textured. I am having difficulty with running animation on the object unless I use Bones on the model. But for some animations this would not suffice. Some are just basic 3d animations.

Can anyone describe the workflow of using 3ds max or a 3d tool to export an animated 3d model for loading using ofxAssimpModelLoader and nay animation limitations it may have?
