Version 1.1.0 - 2026-04-09
Added
- Added support for an optional end cross-section guide for cross-section mode interpolation.
- Added Start/End Bias control (-1.0 to 1.0) to tune how guide influence transitions across knots.
- Extended validation and warning checks to include end-guide topology and start/end guide open/closed mismatches.
- Added automatic knot-count balancing between source splines during blend generation.
- Added warning prompt when automatic resampling is applied.
- Added support for 3ds Max 2027.
Changed
- Improved spline handle blending with a selectable mode:
- Legacy (absolute handle interpolation)
- Direction + Length (directional interpolation for smoother transitions)
- Added non-blocking topology warning when guide spline open/closed state differs from rail splines.
Improved
- Hardened guide-frame math for degenerate and near-collinear cases in cross-section mode.
- Enabled animation for easing parameters.
- Added right-click clear behavior for cross-section pickers in the plugin UI.
UI/UX
- Added dynamic cross-section guide status hint in plugin UI.
- Added checkbox tooltips for major options.
- Updated cross-section controls to enable only when a guide exists and cross-section mode is enabled.
- Updated cross-section UI labels to explicitly distinguish start and end guides.
- Updated cross-section tooltip copy to reflect start/end blended guide behavior.
Fixed
- Improved guide UI state refresh logic so controls enable only when required guide inputs are valid.
