Make sure that the material you’re using for your particles is set to any sort of transparent shader. Second make sure to check ‘alpha is transparent’ in the texture import settings.

It should work if the image you use is a .png.

NOO mien wotn workl1!

If your sprites are in the .png format,

then in your particle system “Renderer” Section, set the material to “Sprites-Default”.
