Hello!

Does anyone have information or maybe a tutorial on how to create a shader effect like the one attached on this thread?

I don't need the AO/shading effect just more of the outline/wireframe effect shown.

Thanks!

It looks like the gag of a back facing copy of the geometry that's slightly larger than the original, and draw with hidden backfaces. Giving the illusion of an outline, when really you are seeing the inside of a slightly larger hollow copy.

Don't the toon shade setup nodes they added to Houdini a while back enable this effect?

You are probably aware that you need to make a copy or an instance to use the toon shaders. There are some shaders you can create that will do this all in one step, but here is an example of use of the two shaders.
