Edge detecion Wireframe effect

Hey guys,
im trying to get a Wireframe/Tron like look for my models… the problem is it wont work with the ■■■■■■ youtube tutorials where they just make it possible for cubes :P… so post process (i havent tried it…) i think will destroy my scene… by changing colors into much smaller levels… so it looks than like a Tron world but cartoon like.
I tried it with baking the mesh itself into wireframe… but stupid triangles on flat area destroys the look :P…

Any idea how to do that… and its possible! i saw it somewhere in a game… but dont know the name…
But Thanks for any help.
PS: Dont send me the ■■■■ tron youtube link… like everyone i asked did haha…
