I make the scene by starting the first step with all channels disabled. I then enable the channels I want to use in the first step, and set their values. I then add a new step, which copies the first step into the new step. I then enable the channels I'm adding into the new step, and set their values. I do the same with the third step, which completes the scene.
Conceptually, I figured that individual steps within a single scene should behave similarly to how multiple scenes interact... And again, this all works in 6.32, which sort of led me to the conclusion.
Now, I'm hoping that this type of functionality stays, as it's sort of what the majority of my chase scenes are designed around... lol!
Thanks, as always, and let me know if there's anything further I can do to assist.
