This macro lets you directly control particle acceleration, speed and spin.

For example, you can make the particles move faster and slower, start or stop spinning, rotate to a certain degree or just freeze at any time.

very nice work!
thanks for sharing this. very appreciated.

cheers!

EDIT:
However in Your Comp i get the "particle cannot be branched" error and Your tools is not working ?

EDIT2:
also when adding the tool to the script, it nullifies pEmitter velocity. i'm using fu 6.1, should only work for 6.14?

yep, me too.
however, looking through vfxpedia notes, they "added ‘delta’ variable to pCustom expressions, for taking time deltas into account" in fu 6.14.
probably Gringo's tool is using this so the tool is working only with fu 6.14 :(

too bad.

Great tool nonetheless

Yes, I forgot to mention this macro is for Fusion 6.14 or later.
Eyeon introduced some great improvements not only in the particle system, so I would highly recommend using it.

Just as Marek said, I use delta in my new tools to get expectable result with the Motion Blur and Sub-Frame Calculation Accuracy turned on.


However in Your Comp i get the "particle cannot be branched" error and Your tools is not working ?

Yes, this is the common problem of any particle macros in Fusion. Regardless the annoying message, the tools work. I hope, someday Eyeon will suppress this message for the case of macro inputs instancing.

In this new version you can control particle size too:

I think of making a new tool which would set particle properties like position, orientation, size, color and others explicitly using regions and weight...
Could be useful.

It can define the properties using interactive viewport controls, for example...

Hey guys, Is there a way to retime a particle solution?

I have a shot in which the Fusion 3D camera is in the center of confetti-like particles which slow down into bullet time for a while and then speed up back to normal speed. While this happens I need to animate four 3D objects which move in the same shot but independent of the retimed particles.

Any ideas?

Does the retime3D fuse work with particles?

I used the retime3D from Krokodove but it doesn't interpolate particle positions between frames. :(

Unless you are referring to another retime3D tool.

That's because the particles don't have positions at those inbetween frames unless you explicitly make them. How many subframes do you have calculated in your pRender?
