Houdini 21.0 Nodes Dynamics nodes

Muscle Update Vellum dynamics node

Update time-varying Muscle geometry and constraint properties inside a Vellum Solver.

Since 21.0

This node allows you to recreate the behaviour of a Muscle Solver Vellum SOP inside a regular Vellum Solver SOP, when used in conjunction with a Vellum Configure Muscles SOP.

It ensures that time-varying Muscle properties, such as fiberscale, velocity stiffness, muscletension, and targetshape activation are updated on each substep of the Vellum simulation.

The typical use case would be to create a Vellum Solver SOP, dive inside it, and create this DOP there. Ensure that the output of this node is connected to the force_output null.

Parameters

Vellum Solver

The path to the Vellum Solver whose geometry and constraint inputs to query the time-varying properties from.
