Troubleshooting

Trimmetry creates nothing

Check that:

• Path is the first child of Trimmetry;

• Profile is the second child;

• both objects can be converted to splines;

• Profile contains at least two points;

• Path has a non-zero length;

• GROW is greater than TRIM when Invert Trim is disabled.

PATH and PROFILE are set, but there is no result

In the tested build, the generator receives its inputs through the child hierarchy. Use:

Trimmetry
├── Path
└── Profile

Segments grow in different directions

1. Enable FIX SEG DIR.

2. If the entire result is oriented opposite to what you expect, enable INVERT DIR.

3. Then check ANCHOR SORT MODE and DIRECTION.

The segment order looks random

For diagnostics, set:

• SORT MODE = BASE;

• INVERT = -;

• ID OFFSET = 0;

• GAP = 0;

• MERGE PAIR = OFF.

Then enable the settings one at a time.

Too many segments were merged

Reduce SEARCH RADIUS LOCAL/REAL and MAX NEIG. Remember that overlapping pairs merge transitively: the pairs 0+1 and 1+2 create a single group of three segments.

The texture jumps during Grow

• UV MODE = LOCAL stretches the entire texture over the currently visible portion;

• UV MODE = GLOBAL preserves alignment with the overall progress.

GLOBAL is usually more stable for an animated Grow. If the direction changes because of Trim or Bounce, try UV INVERT = AUTO.

A seam is visible on a closed path

Make sure that:

• Path is actually closed;

• a closed Spline Type is used;

• GROW = 100% and TRIM = 0%;

• INVERT TRIM = OFF;

• Profile has a consistent point direction.

Profile jitter or kinks

Increase Path detail, enable FIX SEG DIR, and compare ROTATION MODE = NORMAL with MATRIX. For smoother shading, check Phong Angle and Angle Limit.
