Users can run 3ds Max in Batch mode, which allows you to perform MaxScript or Python automation in the background as a standalone process or in parallel with the desktop application. Spline Mirror will create a duplicated version of the spline across a mirror axis specified with a gizmo. Spline Overlap detects self-intersections of splines and displaces overlapping segments creating an overlap or piling effect. The Spline Morph modifier provides Progressive and Blended morphing options for splines. The new additions to spline tools also include several new modifiers. This tool can be applied based on soft selection values. The Spline Relax function for splines smooths out spline knots and their associated handles.
The Influence helper object works with Spline Influence to provide distance-based soft selection information. This functionality is useful for applying subsequent modifiers selectively across the spline. The Spline Influence tool permits the soft selection of spline knots based on proximity to other objects in the scene. Since this process is computationally intensive, this tool includes a “Create” function to generate a pre-computed duplicate of the final result. Optimize Spline is 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. Options include the ability to animate the twist along the path of the spline as well as having the deformed object adopt the Material ID of the underlying spline. This modifier operates in Object-Space so that the modified object conforms the selected spline path.
Path Deform enhancement is an extensive update to Path Deform. This tool also adjusts soft selection values.
This tool provides a number of advanced options, including the ability to specify knot count as well as the ability to optionally retain nearby knots within a certain tolerance. Normalize Spline additions is an enhancement to the standard Normalize Spline.
With the new Freehand Spline tool, you're able to draw splines in the viewport “freehand” with knots automatically added.
