Making parts of soft body "kinematic"

[ZZpbt.]

It's because object tests (with points) makes only those parts of the flag being sent to another event where they move with pole (with object bind).
Just replace object test with surface test, and pick a cylinder.
That way , parts of the flag, all along (close to the cylinder) will be transferred to next event.

I hope you understand the principle (object tests sends basically parts of the flag that are close to pivot point of the objects... surface test sends particles that are close to actual surface mesh).

If it's not clear, feel free to ask, and I will elaborate more.

Yes please. I really have difficulties understanding the concept off particle systems. All i know is that you do everything with particle interaction, but i dont get how you control this.
