Lookat particle node

Turns this node on and off. The node is only active if this value is greater than 0. This is useful to control the effect of this node with an expression.

Note that this is activation of the node as a whole. You can’t use this parameter to deactivate the node for certain particles.

Only affect a group of points (created with, for example, a Group POP or Collision POP) out of all the points in the input.

How to orient the input particles.

Transform space in which to interpret the Direction parameter.

Object in whose local space to interpret the Direction parameter, when Reference is “Reference object”.

Vector for the lookat direction, interpreted in the space specified in the Reference parameter above.

The vector’s origin is at 0, 0, 0 in the Reference space. As an example, a direction of (0, 0, 1) means a vector pointing down the Z axis.

The seconds a particle in the template has been alive.

Acceleration of the particle.

The point’s relative position in the bounding box.

Point is dead.

Processing iteration number.

A collision for this particle was detected (for example, by the Collision POP) during the processing of this timestep (that is, this iteration of the particle simulation). This variable is cleared at the beginning of each timestep. Note that the collision POP actually detects any collisions which would have occurred the during the previous frame.

Percent of total life used (from 0 to 1).

Expected lifetime of particle.

Point or vertex texture coordinates.

Total number of points.

Total number of points in source group.

Normal vector.

The point number of the currently processed point. The PT is not constant like ID; it changes based on the number of points.

The rest position.

The sliding state of the particle.

Elasticity of a point.

Point is stopped.

1 if particle is stuck to a collision object.

Spring tension.

Time increment.

Point position.

Surface UV values.

Velocity direction.

Point spline weight.

Distance from particle to last collision.

Diffuse color at the collision point on the surface the particle collided with.

ID for last collision. You can control how this attribute is set in the Collision or Limit POP to help distinguish types of collisions.

The time at which the last collision occurred.

The texture map UV coordinates for the surface location where the last collision occurred.

The normal at the surface location where the last collision occurred.

World space position of the last collision.

The UV coordinates for the surface location where the last collision occurred.

Number of times the particle has collided.

Point or vertex alpha value.

Diffuse point or vertex color.

Attractor point.

Charge of the particle.

Point is clinging to geometry.

Point drag.

Leader to follow.

Point mass.

Particle Scale.

Non-uniform scale.

Either the point number or id of the particle nearest to this one.

The distance to the nearest particle.

The number of particles within a specified proximity to this particle.

Rotation angle.

Rotation axis.

Generation.

ID number, which always remains constant.

Original Source point was birthed from.

Parent’s ID Number.

Maximum speed.

Minimum speed.

Sprite rotation around view axis (in degrees).

Texture coordinate of sprite’s lower-left corner.

Size of sprite in texture space.

Sprite scale.

Suppress default position rule.

Suppress default velocity rule.

Suppress default up-vector rule.

Suppress default aging rule.

1 if particle is suppressing its default rotation rule.

1 if particle is suppressing its default angular velocity rule.

Previous velocity.

Up vector.

Absolute speed of particle.
