Camera tracking: how can i render the emession reflection only ?

Hey guys whats up!

Im struggling here with an problem, that is taking me ages to figure out, yet without any sucess ._.

So my question is: Is there a way to render an emession light from an object, but keep the object transparent, so to say, the emession from that object it shown in the render ?

Maybe bad explained, here is link to Blender stack exchange

Object properties -> ray visibility: camera.

Yaawwn, i really explained it baad :smiley:

I actually wanted to render the ermission light with the Cube, so the reflection is rendered, instead of the shadows. Well because, it looks a hole lot more realistic. But hey, thanks for the answer anyways mate ! <3

Maybe Object properties -> ray visibility: shadows ?
