Blocky particles?

[Fundo!]

Im starting to experiment with basic sfx creation but ive noticed that my particles are little squares rather than the other shapes on the texture? What am i doing wrong, ive used what i think are suitable ingame textures, My filter mode is additive so the alpha should be phased out?

some textures do not work with additive/add alpha.
Try to use blend/modulate in these cases.

then they turn into black blobs, all the textures are just squares with color... What is wrong
Nvm it was just certain random textures that had to be used horizontaly rather than vertically

Which texture do you use?
