Spline Refiner plugin for 3DS Max

Spline Dynamics has released Spline Refiner, a plugin for 3DS Max that subdivides splines without changing their fundamental shape. It works by adding detail only where is needed and claims to produce better results than either 3DS Max’s legacy Normalise Spline modifier or the new version introduced in Max 2019. 

The plugin is compatible with Max 2012 and above and costs $7.50. Read more on Spline Dynamics website and see a demo on Vimeo.
