GoalShape Constrained to Target Shape

Feature Overview

In cloth simulation, the GoalShape feature allows you to add constraints to a specified target shape. GoalShape can enhance the skinning effect in the skinning and simulation blending function by converting simple skinning bound to a character into inherited skinning of the rendering mesh itself.

Usage Steps

1. Configure GoalShape Skeletal Mesh

   • The GoalShape skeletal mesh should be a clothing item with skinning information (bound in DCC).

   • This way, the simulation mesh will be bound and constrained to the GoalShape.

   

2. Enable GoalShape Constraint

   • For the panels that need to be constrained to the target shape, enable the constraint.

   • Paint the Attach weights, enable Attach, and uncheck Attach Obstacle.

   • If Attach Obstacle is checked, the skinning information from the Style3D component (bound to the character) will be used as the constraint.

   

3. Mount the GoalShape Skeletal Mesh and Animation under the Main Mesh

   • Add a skeletal mesh component at the same level as Style3D.

   • Add the GoalShape mesh and configure it with the same animation as the main character.

   

• Set the GoalShape mesh to be hidden or visible as needed.
