Houdini 20.0 Nodes Geometry nodes

Set T-Pose geometry node

Stores the rest position for the input bone, muscle, or tissue geometry.

Since 19.0

Warning

This help page is a work in progress.

This node sets the rest position or t-pose for all points on the animated geometry (input 1) to the rest position of the static geometry (input 2) and then stores that information using the tpose attribute.

All constraint connections for any downstream geometry in your Muscle & Tissue network are established using this t-pose position.

Tip

We recommend that you place your static geometry (input 2) at the scene origin (0,0) in world space. This will make things easier for if you are planning to mirror your character’s geometry somewhere in your Muscle & Tissue network.

Example: Rest position bones and animated bones at their starting locations in world space

Attributes

tpose

point

Stores the rest position information for the bones and muscles in the Muscle & Tissue system.

Parameters

Mode

Preset to Store Rest. Creates the tpose attribute, copies the current position and transform point data from the static geometry to it, and then saves the attribute to the animated geometry.

Rest Attrib

Specifies the name for the rest attribute used by the Muscle & Tissue system. By default, the name of this rest attribute is tpose.

Note

The other Rest Position SOP parameters that are listed are not used by the Set T-Pose SOP node.

Input

Input 1

Animated geometry. This should be the geometry you want to constrain. For example, like the animated bones.

Input 2

Static geometry. This should be the position in world space or the pose you want your geometry to be in when you establish its constraints. For example, static bones in a t-pose.

Output

Output 1

New tpose rest pose for the animated geometry (Input 1).
