Question

So I looked at different shaders and posts for how to create an outline around a 3D object in scene, but none of those seem to work well.

What is the go-to method for creating outlines for 3D objects right now? Is there any?

Basically this if for marking 3D object in the scene as interactable when the player gets close to them.
