Houdini 20.5 Nodes Geometry nodes

Muscle Paint geometry node

A stroke-based paint tool for modifying muscle attributes.

On this page
Since 19.0

This node creates painted mask regions for various muscle constraint attributes.

Parameters

Group

Specifies the geometry group to paint on.

Display Group

Visualizes the unpaintable regions of the muscles in the viewport as red muscle regions.

Attribute

Selects which muscle attribute values to paint.

Muscle End Mask

Paints values for the Muscle End constraint.

Muscle to Bone Mask

Paints values for the Muscle to Bone constraint.

Tendon Mask

Paints values for the Tendon Mask Radius constraint.

Muscle Glue

Paints muscle glue constraint properties. You can use this parameter (muscletomuscleglue attribute) to create a glue constraint between neighboring muscles that is more rigid than the regular Muscle to Muscle constraint. While the regular Muscle to Muscle constraint behaves more like a spring, the Muscle Glue constraint has a much higher stiffness connection. If you want a selection of neighboring muscles to never be able to separate, then use the Muscle Glue constraint to attach those muscles to each other.

Muscle to Muscle Slide Rate

Paints the values for the Muscle to Muscle Slide Rate constraint.

Muscle to Bone Slide Rate

Paints the values for the Muscle to Bone Slide Rate constraint.

Reset All Changes

Removes any muscle attributes values you painted with the current node.
