Drawing background once in Unity

Hi everyone ! What’s up ?

I wonder if there is a way in Unity to sort of draw with gameobjects in game mode. I don’t know to excatly put it into words, but I mean drawing background (color/skybox in camera) once and then as gameobject moves, it leaves a track behind itself.


With above example it should be clear.

Anyone has any ideas? :3

Don’t clear the camera buffer between renders…
