What would you call a heirarchical prop, such as an office chair with adjustable height and seatback? If it's a PP2 file with lots of parts, I'd say that was a parented prop. I always thought the difference between a prop and a figure was whether or not there is a skeleton Kinda. You can have a figure without them. Like when you need to make something static, but it needs to conform rather than parent. Or be able to bend. Mostly though I use the filetype to denote what things are, thats the easiest way. Personally I try not to get to bogged down what's called what. I'll use whatever works best for a project. For example on my UFO freebie, so the user can easily change things, I used a mix of prop like figures and parented smart props. Mostly it's about having fun :)
