Simulate cloth with NVIDIA Cloth

With NVIDIA Cloth in Open 3D Engine 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.
  • 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.
