Segment Sort

Segment Sort determines the order in which segments or segment groups (pairs) are processed. Sorting does not change the shape of the original Path; it changes the animation sequence.

REINDEX SEGMENTS

SORT MODE

BASE

The original segment-index order.

REVERS

Reverse index order.

X / Y / Z

Sorts by each segment center’s coordinate along the selected world axis.

CIRCLE

Sorts by the polar angle of the center. CORRECTIONAL PLANE selects the projection: XY, YZ, or XZ.

OBJ

Sorts by distance from the segment center to REF OBJ.

MIRROR

Takes items in pairs from the beginning and end of the ORIGINAL list, creating a mirrored sequence. If the original segment sequence has custom indexing, this mode may behave incorrectly. The example below shows MIRROR sorting with correct original indexing.

Example of reproducing MIRROR behavior by using REF OBJ mode

INVERT

Reverses the final group list after the primary sort.

REF OBJ

Shown for OBJ and used as the distance reference point.

CORRECTIONAL PLANE

Shown for CIRCLE and defines the plane used for angle calculation.

ADVANCED SETTINGS

GAP

Combines every GAP + 1 adjacent groups into one time group. For example, GAP = 1 combines groups in pairs.

ID OFFSET

Cyclically shifts the sorted list. Values can be positive or negative.

MIRROR DIR

Swaps the left and right parts of each pair in MIRROR mode. This is mainly useful when the number of groups is even and the processing order of the final groups needs to change.

PAIRS

MERGE PAIR

Enables merging nearby or manually listed segments into shared groups before sorting.

SEARCH METHOD

LOCAL

Compares distances between centers on a scale normalized to the maximum distance between segments.

REAL

Uses actual scene distance.

SEARCH RADIUS LOCAL / REAL

The automatic-search threshold for the selected method.

MAX NEIG

The maximum number of nearest neighbors added for each segment.

ADD EXTRA and PAIR IDS

Lets you add groups manually. Syntax:

0+5, 1+2, 6+7+8

Numbers are zero-based segment indices. Commas separate groups, and + joins indices within a group. Overlapping groups merge automatically: 0+1, 1+2 becomes a single 0+1+2 group.
