How do I make an entity render only to one player?

[lament marten]

I'm trying to make something that allows the player to pretty much have the warden's vibration detection thing, so i have it set up so every 6 seconds or so, it summons an entity at all nearby entities positions, and it has a special material that makes it visible through walls, but the problem is, this entity is visible to everyone, is there a way to make it only visible to the player who created them? (its only an entity because of the material, otherwise it would be a particle)
