It would be absolutely wonderful if there was a [checkbox] on the stepper/firework properties tab that allowed us to select between whether the angles chosen are relative to the position of the lines and points; rather than the world.
Example: I’ve placed 5 lines on my show scene. Each radiating outward from a central point. Choosing what angles to use at the start/end of each stepper line so that they are all the same (relative to each other) is extremely difficult.
Likewise - if I have to move those position lines later - I also have to go into each and every stepper and adjust the angles to match the position changes. That has proven to be exhausting.
