Simulate cloth with NVIDIA Cloth

With NVIDIA Cloth in Amazon Lumberyard you can create realistic cloth simulations for entities that contain Actor or Mesh components. The NVIDIA Cloth gem provides a component you can use to simulate cloth on any mesh that has been processed with a Cloth modifier applied in FBX Settings.

To use NVIDIA Cloth you must enable the NVIDIA Cloth gem.

NVIDIA Cloth features

• Apply cloth data to meshes imported from .fbx files.
• Add cloth simulation to entities containing Mesh and Actor components.
• Cloth mesh simplification and static triangle removal allow you to use complex cloth meshes and yield faster cloth simulation.
• Define Inverse mass, Motion constraints, and Backstop per cloth particle with vertex color streams you create.
• Blend between cloth simulation and actor keyframe animation with motion constraints.
• Add cloth colliders to actors with Animation Editor.
• Add local wind forces to your cloth simulations or use force regions to simulate wind.
• Simulate cloth in parallel across available CPU cores, or simulate cloth on a discrete GPU that supports NVIDIA CUDA (Windows 10 only).
• NVIDIA Cloth gem’s public API allows other systems and gems to access cloth simulation functionality.
• Debug cloth simulations and constraints with real-time cloth debug visualizations.
