• The SplineTrackMaker is a tool that enables you to create tracks in 3ds MAX by utilizing Splines Shapes. These Splines shapes are vector lines that utilize mathematical calculations to generate curves and lines. This allows for a more organic and flexible modeling approach compared to meshes.
• The importGEO script is capable of importing geographic coordinates (latitude/longitude) based on the World Geodetic System of 1984 (WGS84) datum. The coordinates are provided in decimal format (40.446195, -79.948862, 100.4), with altitude measured in meters. Supported file types for import include KML, CSV, and GPX.
• The Tools Box, previously known as MMtools but now discontinued, offers a collection of tools for general use in 3ds MAX. Some of the tools included are Align, Node tools, Move2SPLINE, Move2POINTS, Move2SURFACE, RANDOM, PATH tool, UVW from mesh, Create Lines f/Objects, BOOLEAN, PIVOT, and ClibBoard Points.
