Hmmm, I can see the problem, but the solution is tricky. You’ve created a material and have set a keyframe in that, but because you’re using the material on each object, they all change together. This is like if you’d used a video in AE repeatedly.
So we to try another way. If you right click on any of the objects you’ll see a tag menu within the cinema4D section there is a compositing tag (I think that’s where it is) if you add that to one of your objects that’s got a keyframe option for visibility. This will turn on and off the object based on the key frame and then obviously you could copy that, onto the other objects. But if you’re wanting an object to be there with a different colour you’re probably going to have to have a duplicate of the whole DNA strand, and make it slightly larger so that it can be in the same space.
I know that there is a bunch of mograph options in C4D light now. Before you didn’t have any mograph and needed the full studio, so I’m not sure but there might be a mograph setting or tag that would do this for you.
