Question How to create scatter effect in unity (without VFX graph)

I would like to create a scatter effect just like in adobe after effects but without using VFX graph (I want it to work on webgl and it seams VFX is not working there). I guess particle system would be a good fit but I am not sure if it is possible to do it like that.

 

should it look something like this?

*but that one uses geometry shader, so might not work in webgl.

in unity particle system, you can spawn from mesh surface,
and at the same time could have dissolve shader in that mesh (to make it disappear).
(not sure how realistic that would look though)

 

Is there a way to do it on 2d image?

 

is that quad, sprite or UI?

 

I would prefer UI but if not possible I can probably make it with other 2.

 

In the end I set particles shape to sprite and use wanted sprite for a sprite and texture field.
