Hello
I need to make the particles being emitted from my material shrink over time.
I can make them all shrink at the same time, but i want them to shrink from the time each particle is emitted individualy, does anyone know how i may do this?
Thankyou so much for your time
After you have added a particle system, when you go to the texture tab you will be able to ad a particle texture.
Add a blend texture and set the blend from white to black.
Set the mapping Coordinates to Strand/Particle and the texture influence to Size
Over the length of the particles age they will change size from o to 1
wow it is that simple 
thankyou so much
