Nice. I wonder if you can change the footfall sounds? This isn't like LBP in that the materials represented real world materials and so the sounds were baked in. Yes, you can change the way the material looks (waxy, classy, metalic etc) but they don't have inherent properties until you set them yourself. Perhaps the settings I mentioned give you generic footfall sounds such as metalic but what about if you create a beach of shale or long grass? Obviously the marionette has collision. How much control do we have over those footfall collisions though?
