K_age variation has no effect?

Postby nathans » Thu Apr 29, 2010 5:18 pm

I ahve been trying to use the K_age daemon, with variation. But the variation seems to have no effect.

Ex 1:

age: 10
var: 0

particles die ten frames after being emitted

Ex 2:

age: 15
var: 5

particles die ten frames after being emitted


Will I need to script my own daemon or am I somehow using this one improperly?
peace

The k_age daemon variation do have an effect, but don't forget it's realflow and it could be a bug or something. From my experience, the variation is applied at the end of duration with a middle bias, for example u have 10 frames duration and 5 variation:


duration - 1 2 3 4 5 6 7 8 9 10
variation - 1 2 3 4 5

so ur particle can live 8 9 10 11 or 12 frames. Retry the k_age daemon in another scene and check that u have proper interaction between the emitter and ur daemon.

K_age variation has (almost) no effect

I just made a test scene with two emitters side by side, one with k_age set to ten and the other with k_age set to 100 and variation set to 90.

the emitter with the variation has particles living up to two frames longer than the one with no variation.

well, the k_age daemon always works for me .... Try to create an emitter and a k_age daemon with a 0 duration and 0 variation, and resimulate, increasing every time ur duration with a frame.
