Scale-in particles from birth
#1
Hello!
I'm missing one thing from standard Max particles (pflow), the ability to scale-in particles from birth, from fx. 0-100% over 30 frames.
How is this done in Tyflow?

Regards,
Thomas

You can do that with a Scale operator, either with keyframes or by using the interpolation settings to scale up from zero over time.

Ok, I sensed that the solution was in that direction. I'm just too much of a Tyflow novice to figure out which combination of settings to choose to get what I want.
An very basic example scene would be wonderful to have   Confused

Do you want to scale with keyframes? Or procedurally?

Hmm, in 3DS Max it's built into the flow presets like blizzard and super spray, so it's linked to emit start frame. I have inserted a scale operator into the stack and played with the various settings, without luck.
I guess I want procedurally, this scale up/down should follow the birth frame.

For procedural scaling, you can use the interpolation parameters of the Scale operator.

In this scene I start by scaling particles to zero in one Scale operator on their birth frame, then in a second Scale operator I scale them up to 500% over 20 frames using the interpolation parameters (timing in this operator is set to continuous). Finally using a time test I send them to another event after 50 frames and scale them down using the same interpolation settings.

A huge thanks from me, just what I needed  Smile
As a Tyflow rookie this is a very nice and simple example to learn from.

Thanks,

Hi. I got this working, but it fails after I add a Cloth Bind operator. Is there any way around this? Btw, I only need things to scale from 0-100% over 30 frames, and not scale down.
