Particle Growth Test

[Mala]

Hi,

 

I'm trying to create an effect that grows dandelion seeds over the surface over time. 

 

 

I've used a copy stamp to grow the seed from 0 - 1 for the coloured partic.es At the moment the seeds grow from scale (0 - 1) on the frame (0-100). So when  the point is birthed at frame 50, the scale will be 50% because it's on frame 50.

 

Does anyone know a way in which the particles start the growth from when they are birthed so it's not as uniform? I've attached my .hip file. Thanks in advance!

Hi Mala,

 

Try looking at using the age of the particles to control the growth. If you add an age sop inside your particle network this will give you some attributes that should help you out.

That worked like a charm!! Thank you!!! I just changed $CB to $AGE in the copy stamp!! 

 

THANK YOU!

I've got another dilemma now. I'm trying to animate the seeds flying away however this doesn't seem to work well with the growth of the particle network and the normals of the seeds spaz out before 70 frames. I wanted all the seeds to grow before 70 frames. 

 

I need to have it so the particles are birthed before 70 frames but the normals of the seeds have an unusual motion.

 

I know this is to do with the emission type as it works perfectly when the emission type is all points (look at the details of the source in the particleSIM)

 

However I can't get the growth type effect by using this type of emission.

 
I've attached my $HIP file, let me know what you think.
