Help with particles

I want to make a particle that you can see through something similar to this youtube video for refrence, I’ve tried using glass as thats the only way I think they did it but im not sure

Are you talking about the start with the white space masking the lines? Because I think that they used a model to overlay on top of it, or used a zOffset with another particle or something with that same parameter, but take this with a grain of salt, as I’m not very experienced with particles.

yes the masking lines, im confused by the overlay part

I don’t think it’s a ParticleEmmitter.
It looks like it may be a transparent inverted MeshPart with a transparent .png image on its inner surface.

can you show an example on how this can be replicated?

Sorry, I was looking at the second part of the video, not the hole and lines effect.
The white outlined ‘splatter’ may be a screen GUI image that just gets bigger. It seems to be replaced by a white outer circle at about the 3 second mark of the video, which may be to keep the longer fingers of the splatter from reaching the edges of the screen before the rest of it does.

I’m not too sure about the multicoloured lines though.
