Hi, I’ve been working towards creating a sort of shockwave effect. Currently I have a mesh emitter emitting a sphere every 3 seconds or so and that sphere grows in size over its lifetime then disappears. The sphere’s material is entirely transparent and simply refracts light. However the the true geometry of the “sphere” becomes way to clear as the refraction clearly defines the faces of the sphere to the viewer. I’m looking for a way to make the refraction smooth so the shockwave effect appears to actually be round. How is this done?
