Particles won't stop being squares

Whenever I use a material in a particle effect it just becomes a square that looks like the original texture. I’ve gone through several tutorials hunting for something they’ve done that I haven’t that could cause this with no luck. I’ve also directly compared my work with free content looking for the same thing but still didnt find anything.

Try add this:

how did you set up the material?
Are you using a mask & translucency blending mode?
