I was trying to follow some of the tutorials from The Wow Factor by Andrew Price.
I got stuck in the one with bloom.
The problem is that it refers to layers in blender internal, while I want to reproduce the effect with cycles.
I’ve created a simple scene with a subdivided cube and a image plane: i’ve removed a few faces in the cube to show the image plane that works as an emission and I want to get 2 render:
1-The cube without the imageplane showing, just with the alpha portion of it (black square in the attachment): i achived it with setting no camera in the plane.
2-just the portion of the imageplane showing, surrounded by alpha: this is where i got stuck. What I got was or all the plane showing the full image i don’t need or nothing at all. I just want the black portion showing the image and all the rest as alpha.
I’ve seen that in the wow factor it refers to all-z , but in cycles it does not exist. Any suggestion?
