Welll, frameCount doesn't do anything except counting how much frames have been rendered. Every time you render a new frame, it overwrites the previous one. So no.

However, depending on what you want to do there might be other solutions. What are you trying to achieve?

That would be more sensible.

And yes, if everything you see is generated depending on one variable, then you can of course control what will be rendered by changing that variable. But there's a subtle difference in meaning there compared to your first question.

Good luck with your project!
