Toon/sketch rendering with nodes


edgeombre.jpgViralata has written two tutorials on his site using some of the new features of Blender 2.43 to achieve nice toon and sketch styled renderings. Are you tired of doing the same old photorealistic rendering? Try this out!

The tutorials guides you through this style of Non Photorealistic Rendering (known as NPR) step by step, ending up with good results that replicate hand drawn work quite well.

It's certainly worth learning this and adding it to your toolbox of techniques. Being able to do some NPR is always a good thing.

  1. I don't know if it's possible, but automating this a little more would be quite awesome. The steps are pretty immense. Call me lazy, but if I'm constantly doing this kind of render, I want to be able to make it a script.

    Kind of like how sketchup basically renders this way with one menu option. Minus the cross hatching of course.

    but I love that somebody took time, figured it all out, and then posted an instructional guide in two languages. Now THAT is community my friends.

  2. Looks really great!
    I've done somethings like it, but this way is a lot better.
    Thanks Viralata, and congrats on the splash screen win Mathias. :)

  3. For those who haven't yet, you gotta download and watch the simple animation "crayon" that Viralata did using a similar technique (link: - the bottom thumbnail) It's look is just fantastic! I wonder how adding in a little bit of animation to the texture of the pencil strokes (like what COG teaches in his tutes - would look in such an animation... might have to give that a whirl... ;-)

  4. Very nice, but did anyone successfuly managed to break the constraints of the vertices?
    It would be so cool to have a "sketch" like render using nodes..

  5. @shul: What do you mean with "break the constraints of the vertices"?

    shul> It would be so cool to have a "sketch" like render using nodes..
    Tha (yusing nodes for the sketch rendering) is exactly what Viralata did in his tutorials .. dunno what else you could mean here, sorry.


  6. @shul: I think this could be partially simulated by rendering out the border of each object (e.g with the Object ID pass), increase its size and blur it and "overlay" it with a sketch-like texture (hand drawn or procedural) similar to the process shown in the tutorial.

    I don't know if I'm experienced enough to make this work (or rather "make it look good") but if i find some time I'll try it :)


  7. Forgot to mention: Of course the approach i mentioned above only has very random sketch-lines. These "tangent"-like guide-lines would be very hard to simulate right, especially since you would need to calculate the tangents direction somehow (script anybody?)
