Rendering Contours with Nodes

Daniel Kreuter demonstrates how to set up contour rendering.

Rendering contours in Blender had always been kind of a challenge for me because there are no tools for this (excepted by the Freestyle render engine). I really wanted to find a way for this and so I came up with the technique which I explain int the video.

      Yeah, I saw this and thought, "doesn't the edge pass do pretty much the same thing?" This is pretty interesting, though.

    • It would be great if you had access to the edge pass like other passes for the Node Editor. Would make the built in method of doing contours a little more flexible.

  1. Nice. Was trying this 6 years ago when there was no Cycles yet :) Needed badly a nice toon-ish render and finally combined edge render with yafray (not yafaray back then) like I described here (me as 'Glootamin'): Results (also posted there):
    I guess it's not such a bad direction - if developers would consider it implementing ... somehow ...

  2. I want to thank you for doing this because it made me experiment. I found your method a little frustrating because the line quality wasn't what I liked.

    I think I found a more flexible way. I created another scene in the blend file called shadeless that was a full copy of the original scene. I had a white shadeless material override all the materials and turned on the edge option. Then in the original scene in the node editor mix the output from both scenes.

    What I like about this method is with the BI edge option you can pick the color of the edges. With your method I couldn't find a decent way to change the color of the outline. With this method you could have a separate scene for each outline color and have separate objects have their own outline colors.

    This is my work around to not having the edge pass available outright. Thanks for sharing! I'm looking forward to doing some NPR renders now!
