I have seen a number of tutorials on Shockwaves and they all look cartoonish to me. I have seen a tutorial by Andrew Price and another one using a plane and a refraction texture animated with noise to create just the heat distortion over a fixed object. What I am trying to create is the expanding blast wave of distortion associated with concussion from exploding munitions in a realistic way.
I have thought about animating donut ring and applying a refraction material so that the ring expands with the explosion. I don't think this will work for my needs since in this case the explosion occurs inside.
I have thought about doing a particle simulation with an exploding blast of particles that only have a refraction material assigned to them.
I'd like to try and create a blast similar to this, created in this Fracture Fx for Maya demo. I can't seem to find an external URL outside of facebook for this video as it wasn't on their website but here: https://www.facebook.com/FractureFX/videos/705143703272645/
