Shadow-Catcher in Blender Cycles: example with documented Nodes
With the release of Blender 2.74 RC comes a great feature: you can attach a text note to a Frame in the Nodes view.
This means you can document your Nodes, right there in the Nodes view. You can put node(s) inside a frame, attach a text note to the frame, and the text note stays with the frame.
To celebrate & to give back to my fellow blenders, I want to share a reusable .blend file that you can easily use to render objects with shadows on a transparent background in Cycles. I learned from web tutes from other kind blenders, and set this up with the new text notes feature – you will see an explanation of what to do, in the Nodes view.
Just put your own objects on the first layer, go to Nodes view and check out the simple instructions.
You can adjust shadow intensity after an image render and save an image without re-rendering.
You can also click a switch to turn on a colored background, instead of transparent, and you can adjust the color directly. No need to put a material on a shadow-catching plane.
Of course, you are welcome to take this example, make it even better, and share!
Thank you, Blender developers.
