Unable to change Node Parameter for each frame

[MOKANA]

I am using the following code to change the scale parameter in a geometry node:

{
s = @scale;

if (s < 1)
{
 if ($FF >= ch("/obj/CONTROLS/Start_Frame_HV"))
 {
  s = s + .25;
 }
}

return s;
}

I am able to grab the value, evaluate it, add .25 to it, and it is reflected on the desired frame.

However, after the very first time, it will not add to it and it stays at .25 until scene completion.

I have tried referencing it via the ch("...") function but it always comes back with a recursion too deep error.

Up until it hits the desired frame, which is 24, the value remains at the desired value of 0. Then at frame 24 it is set to .25, so this tells me that this script is evaluated at every frame, or am I missing something? I am able to increment it from 0 to .25 at frame 24, but nothing after that.

 

Any guidance would be much appreciated

if you are trying to accumulate a value, it could be a good idea to use sop solver instead

You don't need variable s at all.

Replace all occurrences of the variable s with @scale instead. After all, what are you returning s to anyway?

This is running in a wrangle, right?
