How to let particles disappear gradually?

[d4rk3lf]

If you want to disappear like the second sample (being smaller and smaller), you need a scale operator, and you need to animate scale and set it to particle age.

I added a scale operator, could you please show me how to set the parameters?



- Move scale operator to the second event. 
- delete the "delete" operator. 
- Animate scale operator from 100% to 0% (with auto key) in 50 frames, or whatever numbers of frames you want that scale animation is applied to each particle 
- Change sync by to "event" 

That should work.... 

OR... 
You can try just making scale to 0% and play with the interpolation settings. 
I am still unsure how that works, thou. 

Additionally: 
You can add another time test (event based) to second invent, with 100 frames or something, that leads to third event where the delete operator, so you delete those particles that are 0% size.
