velocity

 

 

Use this node to set particle velocity.

 

 

[Inputs]

 

#Particle Stream - This pin requires a particle stream to be connected.

 

Enabled - Enable or disable node evaluation.

 

Mode - There are three methods to change particle velocity.

• Set - Sets new particle velocity.
• Add - Increments current particle velocity.
• Multiply - Multiplies current particle velocity
• Blend ??? Blends new velocity with current particle velocity based on the Blend Rate % value.

 

Speed - New speed to replace/add/multiply.

 

Speed Var % - Speed variation.

 

Affect x - New velocity will affect the x component of the current particle velocity.

 

Affect y - New velocity will affect the y component of the current particle velocity.

 

Affect z - New velocity will affect the z component of the current particle velocity.

 

Set Final Speed- With addition and multiplication the resulting velocity might grow with each frame. Enable this option if you want to set the resulting speed. Velocity direction will remain unchanged.

 

Final Speed- Final particle speed.

 

Direction- Velocity vector - direction of particle travel.

 

Direction Var - Direction variation in degrees
