SYSTEM DOCUMENTATION & REQUIREMENTS

💡 This Skill includes references (resource) components.

What problem does it solve?

This skill solves the challenge of manually authoring, validating, and refining physics properties for 3D assets in Universal Scene Description (USD) files, ensuring they behave realistically in simulation environments.

Core Features & Use Cases

Physics Authoring: Automatically applies physics schemas, mass properties, and collision approximations to 3D components.
Simulation Validation: Runs deterministic runtime checks and visual behavior reviews to identify and fix issues like tunneling, instability, or incorrect motion.
Use Case: A developer needs to prepare a complex mechanical assembly for a robotics simulation; this skill automates the assignment of rigid body properties, joints, and collision meshes, then validates the result against gravity and contact constraints.

Quick Start

Use the content-workflow-physics skill to analyze the current scene, apply appropriate physics schemas to all components, and run a validation simulation to ensure stable behavior.

FAQPage Schema

How do I automate USD physics authoring for 3D assets?▼

Automate USD physics authoring by using a skill that infers physical properties and applies physics schemas to 3D assets. It automatically assigns mass properties, rigid body definitions, joints, and collision approximations to prepare components for simulation environments.

How do I validate physics simulation behavior and fix instability in USD files?▼

Validate physics simulation behavior by running deterministic runtime checks and visual behavior reviews on USD files. This process identifies and helps fix simulation issues like tunneling, instability, or incorrect motion under gravity and contact constraints.

Do I need content-workbench integration to run simulation-backed validation?▼

Yes, content-workbench integration is required to execute runtime validation. The workbench enables the skill to render frame sequences, apply schema patches, and perform topology repair to generate canonical physics-ready artifacts.

What is the best way to prepare complex mechanical assemblies for robotics simulation?▼

The best way to prepare mechanical assemblies for robotics simulation is to automate the assignment of rigid body properties, joints, and collision meshes. Running a subsequent validation simulation ensures the assembly exhibits stable behavior under physical constraints.

Can I automatically repair topology and generate physics-ready USD artifacts?▼

Yes, you can automatically repair topology and generate canonical physics-ready USD artifacts. The skill supports complex workflows involving topology repair and schema patching to ensure 3D content is fully optimized for physics simulation environments.
