Simulated destruction with NVIDIA Blast

With NVIDIA Blast in Open 3D Engine, you can simulate destruction by authoring blast assets in SideFX Houdini and creating entities with the Blast Family and Blast Family Mesh Data components.

To use NVIDIA Blast, you must enable the NVIDIA Blast gem .

Note:

NVIDIA Blast for O3DE requires a SideFX Houdini commercial or indie license to create assets. The apprentice license is not sufficient. For more information on Houdini, see SideFX’s home page.

The precompiled Houdini plug-ins supplied with the NVIDIA Blast gem require Houdini 18.0.

NVIDIA Blast features

These are the features that NVIDIA Blast provides:

  • Fracture geometry and author blast assets in SideFX Houdini with the provided Houdini plug-ins and Houdini Digital Assets (HDAs).
  • Create multiple levels of destruction for simulation.
  • Automatically process and quickly set up assets with the provided Python Asset Builder for NVIDIA Blast.
  • Create blast materials to define the forces required to trigger destruction simulation on blast assets.
  • Add NVIDIA Blast assets to entities with the Blast Family and Blast Family Mesh Data components.
  • Script destruction with the provided Script Canvas nodes for NVIDIA Blast.
  • Debug NVIDIA Blast simulations with real-time debug visualizations.
