I have used a prop to show prop interaction in motion capture. Broom was the simplest and the perfect fit for this project and was suggested by one of my classmate.
I used one of my models from a another class projects as a background where the character sweeps the floor and then sits on the bench.
I first got my motion captured then processed and solved it in Blade. Later I brought it to Motion Builder to characterize the character and the rig. I had some issues in con training both the hand on to the broom. i solved it by adding a point constrain and parented to one of the palm.
I then exported the character with animation to Maya and added my background and aligned the scene and rendered out beauty, shadow and occlusion pass and did the final composting in nuke.
