Do any of you good people know how I might create an underwater caustics effect in OB?
I found something specific to C4D the other day that shows a caustics option within Octane Light settings. Is there an equivalent method?

Could you please post the link to the Cinema 4D example?
Thanks.

Thanks, frankmci - I'm only just learning about gobos.
So how would you approach it in an animation? An image sequence of an underwater caustic pattern?

Yes, I'd probably use an image sequence. You can do it with an animated shader in Octane, but for me that tends to be very finicky, when I can knock out a sequence in After Effects in a few minutes. A sequence will also render faster, since Octane doesn't have to covert the shader to a bitmap for every frame each time.
The gobo rout will give you both caustics and nice god-rays without a lot of tweaking, and can render pretty fast without a crazy number of samples.
