Hello. I really enjoyed today's lecture. I'm just asking because I have some questions! 1.Lead body is a rolling effect, so why does it bounce like popcorn when you apply a rigid body to a spear? 2. Why are you making both of the toner red? Can't you just make one red? 3. When you create a cleaner and put the spear underneath, why is it invisible and you need to register the object in the Objects tab? I have a question for you. Thank you.
