Hey guys, Any chance someone could tell me how to keyframe the scale value of the “shape instance” node in PFlow?

THanks,

I don’t have Max in fron of me right now, but off the top of my head I would say use a separate Scale Operetor and animate that. I’m not saying that the scale in Shape Instance won’t work, but because you are asking this question, I assume you are having a problem with it.
Like anything else, turn on Autokey, move the time slider, change the value.
Now the other point to bear in mind when animating Pflow values, that may be the cause of confusion. Where on the time line to set the keys? It depends upon the timing settings in the operator, is it Absolute, By particle age or Event age?

I’d achieve such effect using scale operator in the event you want transformation happens. The scale operator has different ways to apply transformations, you need to use Relative Successive instead Overwrite Once, the default way of how scale transformation is applied.
The Relative Successive type in the Scale Operator scales the geometry down or up in one frame and next frame do it again and so on, so you see how the geometry become smaller as the time goes by.
