Integration : Update Rotation

Menu Path : Implicit > Integration : Update Rotation

The Integration : Update Rotation Block updates particle orientation based on their angular velocity.

Note: If the system uses the angular velocity attribute and you enable Update Rotation in the Update Context's Inspector, Unity implicitly adds this Block to the Context and hides it. If you add your own Integration : Update Rotation Block too, Unity updates rotation twice.

Unity adds a Update Rotation Block when you enable Update Rotation in the Update Context's Inspector.

The Block adds the corresponding angular velocity, multiplied by deltaTime, to the current particle angle:

angleX += angularVelocityX * deltaTime;
angleY += angularVelocityY * deltaTime;
angleZ += angularVelocityZ * deltaTime;

If you disable Update Rotation in the Update Context's Inspector, the system does not change the particle orientation based on the particle's angular velocity attribute.

You can also add the Integration : Update Rotation Block to the Update Context manually and enable/disable it to specify when the System updates the particle orientation based on its angular velocity.

Manually adding the Update Rotation Block lets you manually enable or disable it.
