Omniverse

The 3D models and PBR textures from A23D are fully optimized for NVIDIA Omniverse applications. Models ship as USD assets and PBR sets include native MDL (Material Definition Language) files, so they integrate into Omniverse projects with minimal setup.

Frequently Asked Questions

Common questions about using A23D assets with NVIDIA Omniverse

Do I need a plugin to use A23D assets in Omniverse?

No. Omniverse natively supports USD scenes and MDL materials, both of which A23D provides directly. Drag a .usd, .usda, or .usdc file into the viewport (or reference it into your stage) and the materials light up automatically under RTX rendering.

Which file format should I download for use in Omniverse?

Choose .usd (or .usdz) for the cleanest Omniverse experience — USD is Omniverse's native scene format and preserves hierarchy, materials, and references end-to-end.

A23D .fbx and .gltf are also supported through Omniverse's importers if you prefer a different exchange format.

How do A23D materials work in Omniverse?

Each PBR texture set ships with a native MDL material that wires the maps to the correct channels — Albedo, Normal, Roughness, Metallic, AO, Height, Opacity, and Emissive. Drop the .mdl onto a prim in the stage and Omniverse RTX renders it accurately, with slider controls for tint, tiling, roughness scale, and bump intensity.

Can I use A23D assets in Omniverse Kit applications (USD Composer, View, etc.)?

Yes. Because A23D assets are USD + MDL, they work in any Omniverse Kit application — USD Composer (formerly Create), USD View, USD Presenter, and the Isaac Sim and IndustrialTwin extensions — with the same fidelity.

Can I use A23D Decals in Omniverse?

Yes. Apply the A23D decal MDL or a generic OmniSurface material to a small mesh or surface above the base geometry. Use the supplied opacity map to mask the alpha. Omniverse RTX renders the decal blended into the underlying material non-destructively.

How do I use A23D IES lighting profiles in Omniverse?

Omniverse supports IES profiles on DistantLight, RectLight, SphereLight, and DiskLight prims. In the light's properties, enable IES and load the A23D .ies file. The luminaire then emits with the manufacturer-accurate beam shape and falloff under Omniverse RTX.

What texture resolution should I use in Omniverse?

Use 4K for hero materials in close-up, 2K for general scene assets, and 1K for distant or background props. Omniverse RTX scales well with high-resolution textures, but tiered resolutions help keep large stages responsive in the live RTX viewport.
