117 bullets hitting the ground which emits sparks from the ground creating a metallic surface collision feel. Also leaves holes on the ground so make sure you check out the preview video for a very simple example and one with a grey background. Animation has alpha channel so place it on any floor you like. In addition I would suggest to color correct the holes to match your floor image, playing around with the grey color wouldn’t affect the sparks so feel free.
