Find parameter value from list to use in expression


Recommended Posts

Hi all,

I'm trying to build a setup that allows me to input an unknown number of blends into a blend shape SOP and will cycle through each blend state one by one based on the current frame number.

So I was imaginging it would go something like this:

if($F == *myCurrentInputNumber*, 1, 0);

I've achieved this by doing it manually by cutting and pasting my expression and incrementing the value by 1 for each input, but I'd like to have a setup that does for me based on how many inputs I have connected to my blend shapes.

Any ideas about how to referecne numerical value of each shape in an expression?

Thanks in advance

Hey guys,

Thanks for the reply's - the issue is that I need this to run through a blend shapes so that each state is recorded as a morph target when exported to FBX, I don't think there other options will achieve this.

So both your solutions are great options, but won't achieve the results I need for this workflow.

Thanks again,
