Thanks, but i already solved it in another way.

yep, i already found this solution. Thicker wasn`t “basic” brush. Thanks for your response.

Mmmm…. not really. I`d like to keep nested comps inside main comp, and match start and end of these comps to start end of main. And also don`t know the exact length of main comp (or rather comps) to set it manually.
In case of using the script you offer I have to keep in mind the length of main comp, then pick the right nested comps from different folders of project to set it for each of them, which is not very convincing. And as far as I understand the length of nested comps will be set from the start, while I need to keep time period currently visible in the main comp.
Anyway thanks for trying to help 🙂

I’ve solved this part of rig in other way. So sorry for disturbing, guys, and thank you anyway.

[Konstantin Kartashov]

? you are funny. I just think maybe somebody met such problem also, becoz to be honest, I already seen such trouble before.
Ok, I`ll try to give you more information.

Thanks for your suggestion, Dan, but I don’t think it will help. I`ll try to explane the purpose of my expressions.
I have keyframe cycle which is controlled in time by this part
valueAtTime((thisComp.layer(“Jim_auto_body”).effect(“Morpher”)(1)-thisComp.displayStartTime/thisComp.frameDuration)*thisComp.frameDuration);

may be you know what is Duik and its function named “morpher”. I think you should be familiar with it, but if not – it is here https://rainboxprod.coop/fr/outils/duik/

anyway this last part should be kept as is, no changes here.

This part
x=thisComp.layer(“Jim_main_ctrlr”).effect(“step_height_correction”)(“Slider”);
y=key(3).value
value=(value-y)*x+y;

controlling the values of keyframes, but the way to keep 3rd key unaltered. These two parts have to control different aspects of actual parameter – value and time. Thus it’s pointless to merge it in one formula. I need two expressions to work here.

[Konstantin Kartashov]

cool! thank you again!

[Konstantin Kartashov]

Thank you very much, Dan,
Everything`s works as needed. Could you please explain what “%” symbol means here?

Mike, your animation sample looks very similar to what I need. Can`t wait to see your tutorial.

[Konstantin Kartashov]

You, Kalle, probably don`t know how it works in 3d-software 🙂 we don`t need here to blend shapes between each other. We may blend each key pose to default pose, and when we blend from one pose to another (both non-default) we just decrease the influence (so called weight) of first pose and increase it on second. Thus we need a single slider for one pose.
Solution with puppet isn`t good for my case, because I need quite big amplitude of animation and I`m sure outputs stretched contours and not very smooth edge.
