Hi,

I'm trying to create a sort of spinning 3d radio wave effect, as if the radio waves were rings moving along a cone that rotates around its point.

Or put another way, like a lighthouse light but the beam is rings rather than solid.

I've tried just moving the mask for the radio waves effect, but that doesn't really work - the waves that have already been spawned move off in their original direction instead of the new one.

Any help would be greatly appreciated!

How about using a particle system like Particular? Spin the emitter and let it fire off custom particles.

Do you have CC? This sounds like a time to use C4D Lite! You can grab a cone primitive and use a gradient of black to white (repeating with no gradation between knots) on the alpha channel of a material.

Thanks for the suggestions guys!

Michael, do you mean texturing the cone inside cinema4d, or can you apply the texture in after effects once it's been imported?

Thanks again!

Ben

You texture your 3d models in C4D Lite.
Here's a quick example: 9075_coneradiowaves.c4d.zip
