Kill Particle

When the Condition value is greater than 0.0, this sets the particle life to 0 and flags it as killed, removing it from the simulation and render.

Modify Attribute

Overwrites, adds, or multiplies particle attributes depending on the Operation selected. This is the primary way of manipulating particle data.

Output Quad

The rendering stage of the particle simulation. Particle data flows into here to draw an instanced quad to the screen. This stage is effectively a Graph Material with access to per-particle data.

Particle ( Get Attribute )

Gets the value of a particle attribute. Use the Attribute drop-down menu to choose what attribute to return.

Particle ( Get Setting )

Retrieves various particle settings that are either set or derived from the Spawn Particle container.

Particle Random

Returns a unique, per-particle random value between Min and Max, extremely useful to get variation in the particle system.

Set Color ( Pixel )

Set final particle color output of the fragment shader.

Set Depth ( Pixel )

Writes a custom value to the depth buffer.

Set Vertex Normal

Set the normal direction vector of the quad surface.

Set Vertex Position

Set the position of the quad surface.

Set Vertex Tangent

Set the tangent direction vector of the quad surface.

Spawn Particle

The spawn stage of the particle simulation. Modify Attribute nodes added to this container are processed for a single frame the moment the particle is created.

Update Particle

The Update stage of the particle simulation. Modify Attribute nodes added to this container are processed every frame the particle exists.
