skydive device looking weird

thank you so much for replying g,
i tried all the steps but it doesn’t seem to work and i think that is because of 2 factors
1 i couldn’t make the shape of the volume device as big as the island maximum scale of it was around 5
2 i couldn’t link the volume device to the skydive one, however there was the option to link the skydive with the volume like the opposite so i tried that and it doesn’t change anything.
once again thank you for replying.
