The prompt behind it
deep cinematic impact
Every preset stays editable. Change a word and the result changes with it.
Impact runs in sound effects generator. The preset is filled in for you and the exact cost shows before you generate.
What Impact actually changes
Freezes the moment of collision, with debris, displaced air and a hard directional light.
When it works and when it does not
Works when there are two objects and an obvious direction of travel.
Fails without a clear cause, because impact without a source reads as random mess.
Getting a better result
Say what hits what, and from which side. Direction is the whole effect.
