I have a scene with a bunch of bouncing balloons and I need to switch materials during animation. The transition doesn't have to be smooth. Just adjusting and keyframing one material won't do, since all the balloons have the same default material, so if I change the material, it affects all the balloons. Here are some of the ways I could think of for solving this, but none of them seems very effective... Option one is to make a copy of the material for every animated object and animate that, but that would leave me with way too many unnecesary materials (one for each balloon that changes color) Option two is to have another balloon with the other material and have them switch places instead of switching the material. Are there any better ways of going about this?
