tySplineMesher Modifier

The tySplineMesher modifier can quickly convert huge numbers of splines into geometry, much faster than 3ds Max’s default renderable spline modifier. It is ideal for tySplines objects, but can be assigned to shape objects of any type.


Geometry

  • Default sides: the default number of side faces created around a spline extrusion. Increasing this value increases the resulting mesh resolution.

  • Render: enabling this override allows you to control the number of side faces created around a spline extrusion at render time.

  • Radius: controls the overall radius of spline extrusions.

  • Multiply by knot radius: controls whether the radius of spline extrusions is affected by knot radius. Knot radius is a custom value passed up the modifier stack by tySplines objects, based on originating particle radii. This option will not work if this modifier is assigned to a default 3ds max shape.

  • Taper: controls the taper value along splines which will affect the radius of extrusions over the length of each spline.

  • X/Y/XY: controls the taper axis.

  • Symmetrical taper: enabling this option tapers splines from the center outwards, instead of from end-to-end.

  • Percent %: controls the maximum percent along splines to extrude geometry. Animating this value allows you to animate the length of an extrusion along the spline.

  • Stretch: stretches the extrusion along a vector that is perpendicular to each spline segment.

  • Offset: offsets the extrusion along a vector that is perpendicular to each spline segment.

  • Rotation: rotates the extrusion along each spline segment’s local axis.

  • Rotation offset: controls the starting point along the spline after which rotation values will take effect.

  • Twist: controls the amount of twist that will be applied to successive geometry cross sections along the length of the spline.

  • Twist offset: controls the starting point along the spline after which twist values will take effect.

  • Normalize twist: controls whether the amount of twist applied is dependent on the length of the spline.

  • Normalize UVs: controls whether UVW coordinates assigned to a vertex are relative to that vertex’s location along the spline.

  • Cap ends: controls whether the ends of an extrusion are capped with faces.

  • Reverse: controls whether the ordering of knots along a spline is reversed.

Orientation

  • From spline: the orientation of geometry cross sections along the spline will be dynamically determined by the spline’s topology.

  • From spline: the orientation of geometry cross sections along the spline will be static.

  • From knots: the orientation of geometry cross sections along the spline will be determined by its knots. Knot orientation is a custom value passed up the modifier stack by tySplines objects, based on originating particle orientations. This option will not work if this modifier is assigned to a default 3ds max shape.

Variable radius

  • Multiply radius by length: controls whether the radius of spline extrusions will be affected by the overall length of each spline.

  • Length threshold: controls the reference length that each spline length will be compared against, when determining how to multiply its extrusion radii.

  • Min mult: the minimum multiplier value for extrusion radii. Increase this value to prevent variable-radius spline extrusions from becoming too thin.

  • Max mult: the maximum multiplier value for extrusion radii. Decrease this value to prevent variable-radius spline extrusions from becoming too thick.

  • Invert: inverts the variable-radius operation.

Materials

  • Override side matID: controls whether side faces will receive a custom material ID.

  • Side ID: controls the material ID value for side faces.

  • Override cap matID: controls whether cap faces will receive a custom material ID.

  • Cap ID: controls the material ID value for cap faces.
