The Update stage of the particle simulation. Modify Attribute nodes added to this container are processed every frame the particle exists.
This node contains a special check box: Simulate. The Simulate option will enable automatic integration of particle attributes to update the particle’s position and velocity. This allows you to simply add Force to your system and the particles will behave naturally.
The default simulation integration is as follows:
acceleration = Particle.Force / Particle.Mass newVelocity = Particle.Velocity + acceleration * deltaTime newPosition = Particle.Position + newVelocity * deltaTime
|Update Space||dropdown||Selects whether or not particle attributes are affected by the VFX Component’s SceneObject transform. When set to Local, particle position, rotation, and scale are transformed by its Scene Object. When set to World, the Scene Object’s transforms are ignored.|
|Simulate||bool||Toggles default simulation behavior, automatically updating particle position and velocity based on force, mass and the previous frame’s velocity.|
