How should i do make particle have different emission angle and the same speed?

Help & Support

I tried to set Local Velocity of Randomize,like this:

But it will make particle have different speed.

And then,i set Start Angle,but it seems not work.Not change anything particle emission angle.

Have i any error setting?

thank you for your time.

I’m not sure if I understand. Are you trying to launch particles at in a specific direction? Or have them rotated at a specific angle?

The Start Angle determines the rotation of the particle when it is created.

The Local Velocity determines the direction the particle move in during it’s lifetime.
