Boomer Labs SplineTools

SplineTools is a 3ds Max plugin that delivers a collection of 9 Spline related tools and enhancements.



Freehand Spline: This new Spline Type allows the user to draw splines in the viewport “freehand” with knots automatically added.

NormalizeSpline2: An enhancement to the standard Normalize Spline, this tool provides a number of advanced options, including the ability to specify knot count as well as optionally retain nearby knots within a certain tolerance. This tool also adjusts soft selection values.

PathDeform2: An extensive update to PathDeform. Most notably, this modifier operates in Object-Space such that the modified object conforms the selected spline path. Options include the ability to animate the twist along the path of the spline as well having the deformed object adopt the Material ID of the underlying spline.

ReSpline: A high quality knot reduction tool that will optimally reduce the number of knots and adjust their handles in such a way as to reproduce the original spline as closely as possible.

Spline Influence: This tool permits the soft selection of spline knots based on proximity to other objects in the scene. This functionality is useful for applying subsequent modifiers selectively across the spline.

Spline Relax: This relax function for splines smooths out spline knots and/or their associated handles.

Spline Morph: New in Version 1.1, this modifier provides Progressive and Blended morphing options for Splines.

Spline Overlap: New in Version 1.2, this modifier detects self-intersections of splines and displaces overlapping segments creating an overlap or piling effect.

Spline Mirror: New in Version 1.3, this modifier will create a duplicated version of the spline across a mirror axis specified with a gizmo.

The plugin is available for 64bit versions of 3ds MAX from 2010 to 2017.

Please Note: The 3ds Max 2018.2 Update Now Includes SplineTools.

What’s new in Version 1.3:

  • Spline Mirror: This modifier will create a duplicated version of the spline across a mirror axis specified with a gizmo.
  • 3ds Max 2017 support

What’s new in Version 1.2:

Boomer Labs has updated its useful collection of spline-related tools and enhancements.

New features include:

  • Spline Overlap – new spline modifier than will detect spline self-intersections and displace knot position to provide a “piling up” effect.
  • Freehand Spline updated – now retains the surface normal obtained during object constraint for modification later, also provides improved normal accuracy
  • Normalize Spline2 updated – freehand normal aware, so that normals are also adjusted along with knots
  • PathDeform2 updated – “Use Normal” option added in cases where the surface normal of the freehand spline is known and available. Allows for “wrapping” an object around another – something Max users haven’t been able to do until now.
  • Max 2016 support
  • Relax – Fixed a defect that prevented the spline from updating in some cases

What’s new in Version 1.1:

Spline Relax:

  • Improved algorithm provides better results
  • Max iterations increased to 500
  • “Show Knots” option added

Freehand Spline:

  • Granularity option added
  • Ability to continue Create
  • Pick Object for Constraining to the surface (with offset)
  • Clone operation fixed
  • “Close” option added

Spline Influence:

  • Add, Multiply or Overwrite options for existing selection weights
  • Selection Modify Options – Convert Selections (with Fall Off)

Normalize Spline2:

  • Option for total versus per Spline knot count
  • “Keep Tangents” option added
  • “Show Knots” option added
  • “Simple Interpolation” option added


  • “Preserve Form” option added


  • 30-50% speed improvement
  • “Show Knots” option added
  • Increased subsegments to 10 (from 8)

Spline Morph:

  • New modifier supporting Progressive and Blended morphing
