How to rotate particles around their anchors?

I want to use radial particle system. I have some object and by clicking on it, a lot of particles should fly out from behind it. Here’s how is it looks like

To set the correct start rotation angle and velocity I use Render mode: Stretched Billboard

And now I want to make particles to rotate around their anchors. As I understand, Rotation over Lifetime can help me. But, setting litterally any number does not affect at all.

Could you please say, why the Rotation over Lifetime doesn’t work and how can I rotate particles around their anchors?

stretched billboard ignores all particle rotations since it will override rotation in the moving direction of particle . unless you are in unity 2020 above in which they added freeform stretching in streched billboard renderer properties. enable free form stretching and disable rotate with stretch.177210-screenshot-2021-03-09-030051.png
