You mention that you’d like mines to have a more natural curve while in the air. Could you explain what the difference is between FWsim and reality that you observe?
You also mention a “falling tail effect”. Do you have a video link, or alternatively, can you describe how that looks like?
fwsim comets (shoot angle 45 degrees) will shoot as a straight line then falls instantly when reaching its maximum height yet real life comets tends to arc
And the tail effect I mentioned, I am no sure whats the exact wording so heres the video link example
You can adjust this initially with the tails under the heading “With” where you can choose the width of the tail.
You can also adjust the duration of the tail if you want.
Although I do advise you if you want a tail like in the video that you need about 5/6 types of tails to make it look realistic
