Is there a way that I can control a specific effect based on a fall off object?
Basically i'm working with this guy who is a long c4d user. He showed me a feature where you can control a bunch of effects or their intensity based on a falloff object. In other word let me examplify…
Imagine i have a bunch of copied boxes in a grid pattern or so. I then apply a transform moving all of them 2 units in the y axis…
What i want is to control the amount of “transform” applied based on the fact if this primitives are inside my fall off object or not…
You can check this example in this image i found in which the falloff object controls the y scale:

I know i can order vertex in x or y, etc but this control volume seems to be a great feature because this can be applied to any effect… Additionaly this system in c4d has like an outter volume for maximum, an inner volume for minnimum and a ramp where you control the falloff. Maybe there's something like it in houdini but I'm not aware of it.
Can you help me?
Thanks.
