I have an object with an UV-map, in this example the box. The background is transparant.
The box reflects on the plane. (and also the shadow)
As final result I only want to see the box with his reflection and shadow on the plane not the plane itself.
So everything else should have to be transparant.
I think what he wants a shadow and/or reflection catcher for compositing purposes. Either for video or a website app where a different background can be loaded in. Not sure if it’s in Blender, but I’m curious to see what the answer is.
I found the solution, but it wasn’t an easy way.
So i needed to have a alpha background so it could be used for compositing in Premiere Pro.
Also the reflection needed to be a little bit transparant, this way it will look natural on every background.
I became result by this combination of nodes. Is there any easier way for getting the result?
(Like there is a dropdownlist with: shadows only --> Reflections only)
