Looking for silhouette material

[ClockworkOcean]

@intrus03

In this video they use a “grid material” that does not detect any edges to make the silhouette.
Since what I am doing requires seeing the silhouette as any STP viewer would, it is not what I am looking for.

Is there no way to detect the edges to make the silhouette?

Thank you very much for your answer anyway.

Naturally in UE you have wireframe view, but that’s not a run time thing.

What is STP?
