I want to combine two render layers and a video clip. In the first layer I got My Object, in the second one I have a mirror. This all is lighted by a hdri, which I checked for Transparent in the render settings. Now I only want to add the reflection from my Object in the first layer to the scene in the Composition. But it reflects the Hdri, too; how can I remoove the Hdri reflection and only ceep my Objects Reflection? I allready tried to use the mixed alpha and GlossInd channel as a factor to mix the GlossInd with the rest (as seen in the picture), but it doesn't work.
