if add a render asset to particle system, i can not rotate it.
any one can help ?
What do you mean by ‘cannot rotate it’?
change entity rotation or any other particlesystem paramaters ,the particle takes no effect
Bear in mind that you have local velocity and velocity curves
velocity is always in world space whereas it sounds like you want local velocity so that the velocity of the particles is in the same space as the local node transformation
You may also want to enable Local Space too
I set all velocity to 0, enable local space,then rotate the entity , still takes no effect ,the render asset (mesh)of particalsystem keep static;

It be best to create a simple public project that showcases the issue

I want change particle start angle by rotate entity rotation.is it possible?
Oh, I see what you are doing here. I’m afraid this is not possible with the current implementation of the particle system besides changing the start/end angle and even then you don’t have control of the axis it rotates on.
seem true and sad 
You may want to try a third party lib like Effekseer: [SOLVED] Canvas-to-PlayCanvas ... Challenge on particles - #12 by Saad_Haider
thanks, I will check.
