With this plugin, you can subdivide the splines uniformly, in a human-like manner, adding detail only where it needs to. So, you get a balanced segments distribution without altering the shape of your curves or touching the existing vertices.

Spline Refiner can process hundreds of splines in seconds, with just a few clicks! This tool will really speed-up your workflow and enhance your work!

This is ideal for CG artists and professionals who usually work with vector curves in 3dsMax, e.g. for Architectural Visualization (Arch-Viz), Engineering, Industrial Design, 3D logo design and spline modeling in general.
