Handles importing existing scene mesh sequences into the Mesh Spline tool. Analyses patterns in TSStatic chains to detect caps, distribution modes, and mesh types, then reconstructs a parametric spline from world positions.

Public API

FunctionSignatureDescription
M.handleDelayedSplineUpdates()Per-frame check for delayed updates after collision mesh rebuild

Key Internal Functions

FunctionDescription
analyseMeshSequence(meshPaths)Identifies start/end caps, distribution mode, and unique meshes
importFromStaticMeshArray(...)Creates a mesh spline from an array of TSStatic positions and paths
extractSplineFromPositions(positions)Fits a spline through mesh center positions with RDP simplification

Mesh Sequence Analysis

The import system detects:

  • Start/End Caps: Meshes appearing only at endpoints
  • Single mesh: All interior meshes are identical
  • Round-robin: Meshes cycle in a repeating pattern
  • Random: Meshes appear in non-repeating random order

Import Pipeline

  1. Collect TSStatic objects from scene selection
  2. Extract positions, rotations, and mesh file paths
  3. Analyse mesh path sequence for patterns
  4. Create spline nodes from position chain
  5. Apply RDP simplification
  6. Set mesh component properties based on analysis
  7. Trigger delayed collision update
-- Import is triggered from the Mesh Spline editor UI
-- via "Import from selected objects" button

Master Spline - Spline Manager

Core data management module for the Master Spline tool. Handles creation, deletion, serialization, undo/redo, splitting, joining, linking, and dirty-state updates for all master splines.

Mesh Spline - Populate

Handles the placement of TSStatic mesh objects along mesh splines. Computes positions, rotations, and component selection for each mesh unit based on spacing, jitter, caps, and distribution mode.
