To gain fine control over hair animation we have the ability to sculpt multiple versions of the same guide hairs and then morph between them. This workflow is very similar to morphing with 3dsmax meshes.
3dsmax 2018.2 update brings us Spline Tools, which provide a spline morphing modifier. In this video learn how to use this modifier together with Ornatrix to achieve guide morphing.
If you have an earlier version of 3dsmax fear not, we also show how to use Ornatrix built-in Edit Guides blending option to morph guide shapes withing a hair stack.
Ornatrix is a complete hair, fur, and feather solution for Autodesk 3dsmax.
