Starfield effect with effect controls, play with the controls to generate new Starfields. The effect is free and available on the C3 addon page.
Ok, so what's happening is that the effect is a pixel shader that is procedurally generating the starfield pattern _instead_ of showing the sprite image. If you put the effect on any sprite it will have the starfield instead of the sprite image. So, for example if you want it as a background, you would make a sprite the size of the background and add the Starfield effect. Then you would change the effect parameters of the sprite to tune the image to look as you wish. Perhaps reading more about effects would help. construct.net/en/make-games/manuals/construct-3/project-primitives/objects/effects
Thank you.
I love this plugin. This is perfect for my game.
