Nodes

Medusa Nodes uses custom-made nodes (node groups) built inside Geometry Nodes.

There are two types of node groups:

Main Nodes

Main nodes affect the hair and guide objects. There are four types of main nodes:

Initials:
Nodes that initially come with every new hair or guide object. They can’t be removed.
Deformers:
Procedural modeling nodes that deform or shape the splines in a realistic manner.
Utility:
Responsible for some of the more technical procedural spline editing.
Simulation:
Nodes that utilize different solving algorithms accompanied with caching.

Generator	Generates splines (hair follicles) on the mesh object.
Visualizer	Visualizes splines by adding thickness and material shading.

Guide	Shapes the hair with the help of the Guide object.
Clump	Creates various kinds of clumps, supports nested-clumping.
Braid	Adds regular and fishbone braids.
Noise	Adds noise-based deformation.
Curl	Adds curls to hair.
Trim	Trims / cuts the hair.

Curves to Splines	Gives the ability to draw and edit Blender’s regular curves objects on Medusa Nodes Hair object.
Mirror	Mirrors the guide and the hair splines along multiple axes.
Scale	Scales the guide and the hair splines by the custom factor.
Resample Hair	Resamples and redistributes the control points in the splines.
Children	Randomly adds simple copies of already existing hair follicles.

Cache	Caches the deformation produced by the simulation or animation, making the playback faster.
Dynamics	Simulates guide and hair splines using custom dynamics solver.

Mask Groups can alter different parameters of the Main nodes, mainly by producing black and white values.

They are not always necessary but can help modulate the effect produced by a Main node.

Texture	Uses painted textures as an influence mask.
Random	Uses a random function as an influence mask.
Percent	Uses a percent function as an influence mask.
Noise	Uses a noise function as an influence mask.
Curve	Uses a Float Curve as an influence mask.
Ramp	Uses a Color Ramp as an influence mask.
