Thx Michael, tried hat but it is still appearing to evenly.
Had another approach with lights as emitters but i am missing to control the particle size by lights..
This is what i am trying to achieve but also moving through 3d space for more depth and also being able to control the twisting. At the same time I am looking for war way to start and end it more naturally (like the example does at the beginning) – not just like masking (which it does at the end) but growing and getting broader and thinner…
