I recently did a graphics job in After Effects and created a globe with a kind of ripple effect that highlighted a region of the world with the ripples dying out as they get further away.
Because I had to zoom in to the globe, I needed to use a subcomp that was 18,000 pixels across and also a subcomp of the radio waves effect of the same size and it was very slow to render. I've finished the job now but I'm interested in seeing if it could be done more effciiently in Blender. Making the globe in Blender using the same large image it seemed much more responsive but I can't reproduce the radio waves effect from After Effects. The wave texture gives an effect where the initial ring diameters are really thick and then getting thinner and thinner as they expand away. And this doesn't look good for what I'm doing. Really I just need circles that generate and then fade out over time but I can't really work out what to do. Blender's 2d effects options seem relatively limited in this regard. I could probably do it by rendering out a texture layer from AE but wanted to keep it as procedural as possible.
