The Move Pivots operator can be used to modify particle pivot points. This is analogous to modifying the pivot of a scene object, if we think of the particle’s transform as a pivot and the particle’s shape as an object.
Shape center: moves the particle to the center of its shape mesh.
Closest point to object (in world): moves the particles to the closest point in world-space to a specified object.
Closest point to object (on shape): moves the particle to the closest point on its shape to a specified object.
Furthest point from object (on shape): moves the particle to the furthest point on its shape to a specified object.
On shape bounds (local): moves the particle to a specified location on its local bounding box.
On shape bounds (world): moves the particle to a specified location on its axis-aligned bounding box.
Offset by value (local): moves the particle in the local space of its transform.
Offset by value (world): moves the particle in world space.
Custom Vector: moves the particle to the location defined by a custom vector.
Closest point to vector (shape): moves the particles to the closest point to a custom vector on its shape.
Furthest point from vector (shape): moves the particles to the furthest point from a custom vector on its shape.
Absolute position (world): moves the particle to an absolute position in world space.
Surface: proximity tests will search for the closest point on the input object(s) surface.
Pivot: proximity tests will search for the closest input object(s) pivot.
Particle Position (fast): the closest point to an input object is found by finding the smallest distance between the particle’s position and an input object.
Particle Shape (accurate): the closest point to an input object is found by finding the smallest distance between the particle’s shape and an input object.
Vertices: the vertices of the particle’s shape mesh will be used to do the closest/furthest calculations.
Edge Centers: the edge centers of the particle’s shape mesh will be used to do the closest/furthest calculations.
Face Centers: the face centers of the particle’s shape mesh will be used to do the closest/furthest calculations.
Value: the amount to interpolate particle pivot positions from their previous value to the new value.
