Animating Frequancy
#1
Hi Tyflow Community, 

Quite new to Tyflow and loving it so far. Amazing software

I have a question to you all. I am trying to create a simulation where the particle birth changes particle shape over time. 

Eg the simulation starts birthing cubes and finishes birthing spheres. I was planning to do this buy adding 2 particle shapes, animating the cube frequency from 100% to 0 and the sphere frequency from 0 to 100%. It seems however I cannot animate the frequency amount? 

Any ideas I could go about this?

Any help would be appreciated. 

Thanks

Not sure what you mean by this? 
How can the particle birth change particle shape? 

As for animating frequency... if you mean, animating frequency of particles being born, you can use regular birth operator, change the method to "per frame", and just animate that parameter.

Thanks for replying d4rk3lf, Ill try and explain better.

Example, I have a car model, from the exhaust its starts with carbon being emitted from exhaust (cubes), as the animation progresses, I want bubbles (spheres) to be emitted from exhaust. What is the best way to do this?

frame 0 - 100% cubes
Frame 100 - 50% cubes and spheres
Frame 200 - 100% spheres. 

Cheers

Rob

I'd just create 2 flows, and just do the boxes and the spheres separately...
Both flows would be basically the same with exception of shape and birth operator.

Hey, yes all Shape properties are static values...and cannot be animated.

To do a swap like this over time, you could rig it up in various ways....d4r3lf's suggestion would be fine...2 Birth events each with their own shape, just progressive decrease the per-frame rate of one while increasing the per-frame rate of the other. Use a Send Out operator in both to send all particles to a single other event if you want to keep them organized together in the same event.
