NdotLight/SimReady_Assets

Welcome to NdotLight SimReady Assets

A collection of OpenUSD assets from NdotLight, prepared for robotics simulation, training, and evaluation in NVIDIA Isaac Sim.

The initial collection comprises 50 template assets, including rigid-body, articulated, and deformable objects for industrial and workshop environments.

What's Included

Asset type	Examples
Tools	Power drill, screwdriver, hammer, wrench, pliers, and calipers
Material handling	Carts, handtruck, pallet, and roller conveyor
Storage and containers	Storage rack, cabinet, container box, and steel drum
Safety equipment	Safety cones, barriers, machine guard, and protective equipment
Deformable objects	Selected cable and flexible-component assets

Simulation capabilities vary by asset. Refer to the individual asset's configuration and validation evidence for supported behavior.

Getting Started

1. Browse Files and versions and download the complete folder for the asset you need.
2. Keep the package definition, metadata, USD files, materials, textures, and thumbnails together, preserving relative paths.
3. Open or reference the entry-point USD at <asset>/simready_usd/<asset>.usd in NVIDIA Isaac Sim.
4. Review the per-asset validation and benchmark results before integrating the asset into your simulation. Use a fixed dataset commit for reproducible evaluation.

Validation

Each of the 50 assets includes validation evidence for the Robotics-Prop profile, version 4.0.0, under <asset>/.metadata/. See the SimReady Central guidance for the submission workflow.

Schema validation

The published simready-validate reports (version 2026.8.0) record no blocking feature failures across all 50 assets. Individual optional features are not necessarily satisfied; inspect <asset>/.metadata/<asset>_validation.json for feature-level results.

Repository Layout

Each asset is published as a separate package at the repository root. The previous top-level assets/ and reports/ directories have been replaced by per-asset packages and metadata.

<asset>/
    com.nvidia.simready.packaging.json       package definition
    .metadata/
        <asset>_validation.json              feature validation evidence
        <asset>_benchmark.json               runtime test evidence
        com.nvidia.simready.packaging.bom.json

    simready_usd/
        <asset>.usd                         entry-point USD
        materials/                          material dependencies
        textures/                           texture dependencies
        .thumbs/256x256/                     preview thumbnails
        .simready/                          validation receipt, where included

Example: a_frame_sign package, validation report, and runtime report.
