Have you ever wondered how to create alpha masks for compositing in Blender?Â Well, Philippe Roubal has written an explanation on how to do rotoscopoing and matte painting in Blender, so check it out now!
Hi ! In the world of Visual Effects, Rotoscoping, Matte Painting and Garbage Painting are necessary and complementary functions. They are used each time a cut-out in the image is necessary, to remove a background or unwanted objects in a shot. They can save a video shot when Chromakey is not possible, or not enough perfect to achieve the desired effect.
I have searched for a long time a good and affordable software to do both Rotoscoping and Matte Painting, but without finding out "The" software, simple enough and matching my budget. So, I decided to dig more in depths with Blender in this way.
Finally, I have built a setup allowing Rotoscoping and Matte painting to be rendered in one pass, and generating a directly usable alpha mask.
This setup is ready to use and provided in a simple Blend file, with a PDF tutorial.
