Size of particles

Hi,

Sorry for my bad english

I’m a beginner in Unity. I’m making a space shooter and I want moving stars in background.

Left, render I get with Unity. Right, render I want.

How can I control the size in Y of a particle ? Or if I can don’t repeat the material.

Thanks you

Inside the particle system settings:

-Under the render tab click the drop down menu “Render Mode”. Change it to ‘Stretched Billboard’

-Change the “Length Scale” under the render tab (it should have just appeared after the above step) to a desired look.

-Mess with the “Length Scale” setting as well as your particle’s “Start Size” to achieve the desired effect
