Outline on mesh?

can you have outlines on mesh similar to the outline toon shader for iPhone?

there is a simple and the 1st method which came out long time ago before shaders where solving it:

  • make inside your 3d modelling app a copy of the object, it will be the one you want to be outlined

  • then flip the normals of it

  • finally you need like in 3dsmax a so called “push” modifier, which blows the object from its vertex informations to all directions, and scale it to your desired dimension! the more you push(scale/blow) it, the thicker the outlines will be! if you have a simple object like a cube or a sphere, a normal scale into all directions (x,y,z) is enough too! but with more complex objects like characters i suggest you to use such a “push” or “blow” modifier!

  • then export it

  • import the object to unity

  • give it your desired material

  • put it over your original object. and there you have it! Works 100%

hope that helped =)
