How can I track a spark’s channel in Batch?

[kepler]

Hi, coming from another softwares I’m very surprised that seems that there’s no way to make a track for a spark channel in Batch cause it’s an independent module isolated. Is there any way to do it??

Thanks.

Unfortunately not and not you are the first one who misses this feature.

You can’t link spark’s track to an other track in Action node for example. But you can copy it and most of the time it helps.:)

Thanks for your response 🙂 Sorry but maybe I’ve not explained me very well. For track I mean “tracking/stabilizer”. It’s related to your response but I’m looking for a way to do it .
I’ve figured out a way to apply a “tracking” tot he spark doing an Action node, track/stabilize an axis and copy/paste the Action axis offset channels to the spark. By the way, I need to offset that with expressions…. not very handy. So, do you know a better way to do it??
Thanks.

I still don’t really understand what’s in your head.:)
But you have a bunch of tool to change your animation channels.
They’re in a box called Curve Functions Box in the manual and it is set to “Reverse” by default. You can find it on the right side of the animation channels.

I’l try to explain me better.
I’m looking for a way to use the Flame’s tracker to follow a given point from a video and assign the resulting tracked motion to a spark’s position parameter.
Hope I’ve been more clear 🙂

I see. That’s easy: do the tracking in Action, copy the x and y position channels and paste them to the spark’s xy position channel. You can manipulate these channels later via Curve Functions Toolbox, no expression needed.
