Start with the task
An asset should be evaluated against the interaction you need to test. A navigation scene, a door-opening task and a picking task ask different things of the same object. Decide which dimensions, moving parts and physical properties matter before choosing how to create it.
simgenerator provides a hand-authored library alongside asset and environment generation. Use the library when a suitable object already exists. Use generation to create something missing from your scene. For a specific real facility or custom object, discuss hand-authoring requirements with our team.
Inspect the library before downloading
Open an item's details to review its available geometry, dimensions, mass, components and package information. Inspect moving parts when they are provided. Check the actual item: a library category or a photorealistic image does not establish the properties of every package.
For a replica of a particular real object, bring measured dimensions and references. Agree which characteristics need to match and how the result will be checked. Avoid assuming that either a scan or an authored model guarantees a particular tolerance without supporting measurements.
Generate, then evaluate the result
Start with a clear brief describing shape, dimensions, materials and intended interactions. Add a reference image when appearance or layout matters. Current generation accepts text and a reference image and produces USD output; it does not yet compose uploaded 3D assets or a selected library collection.
Once generation finishes, inspect the result and review its available properties. A rendered texture is evidence of appearance; it should not be treated as a measurement of friction, density or real-world material behaviour.
Use an explicit validation target
NVIDIA SimReady Foundation defines requirements grouped into features and profiles for particular uses. Our authoring standard follows this framework. Check the profile and version recorded for a package instead of assuming that a generic SimReady label means every simulator configuration has been tested. See the SimReady Foundation project.
OpenUSD's physics schemas describe properties including rigid bodies, collisions, mass, materials and joints. The fields present in a package and their interpretation in your target simulator are the details to inspect. See the OpenUSD physics schema documentation.
Keep the evidence with the asset
Record the source references, assumptions, edits, validation results and simulator version used for your checks. Test the interactions your task depends on. Apply this process to both hand-authored and generated content.
