Rendering Only Caustics

#1

I’m rendering a bottle of water and compositing it into a live scene. I need to render the caustics on a seperate layer so that I can composit it into after effects. I was wondering how you can do this? I see a render specular only option in the layer presets but not caustics.

I really need to find out how to do this, its for a school project.

Thanks for any help.
