Trail behind standing player

As per the title suggest, I want to draw trail behind player in all condition.
At present I can able to draw trail behind player when it was moving using Trail Renderer component.

But I also want to draw trail when player is not moving. If any other way exist to simulate same effect then please suggest this also.

EDIT : Image example that represent my concept. At present my player is moving so that it draws trail behind it.
But if player is not moving than also I want to draw trail behind it.

I want some thing similar to Prewarm in Particle System.


You could use a line renderer. Define its vertex count and width, keep track of your trail yourself and update the renderers vertex positions. Done
