Material mismatch when trying to use alembic or fbx animation

Hi guys,

I seem to be missing something. I've tried a couple of free 3d models with either fbx or abc files included but I can't seem to get them to work.

Each time I import the model and the animation and then add the model to a composite shot and then add the animation to the animation area of the model but they always show material mismatch and don't seem to do anything. 

Does anyone know of a free model with animation the definately works in hitfilm so I can try and work out this problem?
