Yes I updated the shockwave shadercode a little (removed some animations and camera angle view) because I wanted to make it modular, right now it uses a very low poly torus object, it's just for the preview. There's a separate shockwave material in the source which you can use for any of your shockwave objects. Also if you want to increase the number of polygons in torus to make it more rounder, you can do it in the shockwave asset > mesh > increase rings and segments. However I enabled the previous version (v1) project to download if you still prefer the old shadercode for shockwaves.
