Thanks Walter!
Great tip to achieve what I had in mind.
After messing with it for sometime, i realize I was looking for something a bit different. Guess that happens 😛
I am guessing it can be achieved still with particular (where I assign a few different squares as particles)
the look im after is a mosaic of un-even squares in size and color that will cover the screen like tiles

where it takes them around 70 frames do fade from the middle outwards in either a circle shape or a 45 degree wiper direction.


It can be done manually, but due to the pretty common effect and the fact each particle will (hopefully) have it’s own subtle random movement I had to ask in the forum
Again I have attached quick mock ups to illustrate my thought…
BTW With Walter’s tip I got to my first post question, where these squares will emit and push to the corners
(No tile wall and nice circular disappearance)
Thanks all!
