question Object bind

[HHbomb]

Hi,
I wanted to replicate this c4d tutorial ( at the biginning ): https://www.youtube.com/watch?v=_V4dt5QOMHA
When I bind particles it works, but when I bind scale, I have no control ? It make strange scale behavior.

Bind Scale within the Object Bind operator means that particle scales will be adjusted to match the face area of whatever face they're bound to.

So if you bind a particle to a face with an area of 1, and then the face undergoes some deformation that increases its area to 100, the particle will scale to 100. I think that's potentially what you're seeing happening? Hard to tell.
