Break Apart Shader

No replies here yet so I'll start. If this is a vertex shader approach the main thing I'd think about is whether you want the break to be driven by a single scalar value or separate parameters for different axes. A single driver is easier to keyframe in engine but you lose the ability to art-direct the timing of pieces breaking away independently. In Unreal you can expose multiple scalar parameters to a Blueprint and drive them from a curve asset which gives you a lot of per-piece control without complicating the material graph too much. What's your target engine?
