Hello, I try to make some shockwave shader. Just apply the material to a cube with experimental true displacement and a subsurf. Keyframe the scale and it's ok!

Excellent looking stuff! If you are interested, you could use my distortion materials on top of these to make them even more expressive! https://www.blendswap.com/blends/view/78300
Amazing! Thanks for this.
