I am a bit confused how to manage my problem. I have got a setup of a building site with several cameras and about 150 objects. Now I want to emphasize one of these objects by using freestyle. Due to the many objects I created a new scene with only lighting, the emphasized object and another one that I turned to holdout. To exclude all objects except the emphasized one from freestyle by using the collection option is set. This works fine so far.
But I try to assemble one file using the compositing nodes from the emphasized rendering and the rest of the site witout freestyle in just one render. The problem is, when I switch in th object properties the mask option holdout it is set over all scenes.
How can I fix this to decide in which scene the holdout should be used?
Thanks in advance Lutz
And this is what I get when rendering both scenes with compositing. The black area is supposed to be transparant in my resulting picture.
And here is the *.blend file:
