Concrete ground collapse animation with a separated dust render. So you’ll get two different .mov files, one is the ground collapsing other one is just the dust. Check out the preview video to see with and without the dust layer. Made the contours of the ground shattering animation blurry/feathered for easier compositing. Also after the ground shatters and collapses again alpha channel is visible, so you can place anything behind the effect. In my tests in most cases I found that Overlay or Hard Light Modes and some color matching work best in compositing.
