Are there some bugs in Particle System Render Mode "Stretched Billboard"?

Render Mode “Stretched Billboard”
When Transform.scale.x = -1, the particle flips.

Render Mode “Billboard”
When Transform.scale.x = -1. it looks fine.


Render Mode “Stretched Billboard”
Then when rotation.z = 45, it becomes so thin!

Hey @atk_defender ,

Scaling/rotating particles via the game object transform, especially in nested scenarios, can become tricky, with lots of things to consider: order of nested transformation, direction, velocity scale, emission shape, pivot offset application, etc.

In your scenario, the stretched billboard particles as you have observed already behave differently than the regular billboards. You can try changing the scaling mode to Local to see if you get the desired result:

Hope this helps!
