Age with solver

[wilson99]

Hi guys,

https://gyazo.com/6f0d777b1d67ca0ee1a454be01f34855

Above is a gif showing a Cd transfer from a sphere(red) to a grid(black) using a solver.

Is there a way I can create an age attribute for these particles when they turn red. Then after a couple of frames they would revert back to the colour black.

Any ideas would be great, thanks!

Append a point wrangle after your attrib transfer, with this line:

 

@Cd *= 0.9;

 

That will make the colour fade by 0.1 each frame, giving you a fading trail.

This and other solver tricks are covered here:
