Capture reflection with transparent film.

Hi folks.

I’m sure this must have been covered before and I’m probably searching for the wrong thing, I can find similar problems.

I have an object that emits light. It reflects on a plane just below it. The effect is exactly what I want, but I need a transparent background. I’ve tried toggling all the Cycles Settings for both objects, but can’t get what I need.

I have composited blur before, but that’s not really what I want. I could write some software to ‘scrub’ the resulting image and alpha blend each pixel but I’d sooner not have to.

Is there an answer to this one?

Thanks.


i guess this is what you want.
