Control Particle Size on Frame ?

#1

Using the condition utility node, how can I have the particle size grow based on the frame in the timeline ? This is probably not correct, I plug the condition into the firstTerm > Radius of the nParticle ShapeNode, but how do I connect the frame ?
I wouldn’t be surprised if this is all wrong :slight_smile: :sad:

do you just want all of them to change size uniformly as time goes?

you can just goto the radious section on the parti shape node and do it by expression…

“=frame”
but they will get super big super quickly…
or use could make is a bit more of an expression
“=frame/10”
which would slow the size increase…

you could also just plug the time node straight into the radius…or put a math node in the middle to get more control (multiply/divide.)

or do you want to do it per-particle?

in per-particle radiusPP can make a ramp. Its based on the lifespan of each individual particle.

#3

also if you are using a condition node…whats the actual condition you wish to check against?

#4

Expressions evaluate on every-frame, so I try not to use expressions and instead use utility nodes.

Cyberone - Let me try some of your suggestions ! I’ll let you know how it comes :slight_smile:

TThe particles are not emitting, I know something is wrong ?

#6

Connect your time1.output to multiplyDivide and ditch time2.

Remember that you can’t get per particle behaviour like this.

Multiple&Divide node won’t connect to the radius port of the nParticleShape Tool !

Ok

I think that you need to go back to the user manual and read through sections covering particles and particle attributes and how to connect to particle attributes. Especially per particle attributes.

I got it to work, except it’s a space explosion type effect, I’ll have to do more in-depth, good thing is atleast it’s doing something ! :slight_smile:

Glad you got it working.
Allthough you really need to get your head around and start using per particle attributes. It’ll save your ass, I tell ya :wink:

It is working, not exactly how I want it to work, but working none the less. I’ll take your suggestion into heavy consideration regarding per particle attributes :slight_smile:

Hi Falam, is that “timeToUnitConversion1” a custom node?

#13

No, it was inserted automatically ! :slight_smile: Although it may be available in the node editor, that is something I overlooked ! :slight_smile:
