High-level overview of a typical ovrtx application lifecycle. Use when user asks how to structure an ovrtx program, what the main steps are, or how the pieces fit together.
Asynchronous operation patterns including polling, timeouts, and non-blocking workflows. Use when user asks about async rendering, non-blocking operations, polling, timeouts, or parallel rendering.
Creating persistent attribute bindings for efficient repeated writes to the same prims and attribute. Use when user asks about persistent bindings, repeated writes, efficient animation loops, bind_attribute, or updating transforms every frame with caller-owned tensors. Use mapping-attributes when the hot path needs zero-copy direct writes into ovrtx buffers.
Binding materials to prims at runtime. Use when user asks to assign a material, change a material, set material binding, or swap materials on a prim.
Available camera render outputs for Real-Time Path-Tracing (RT2) mode. Use when user asks what AOVs/render vars are available, what format or dtype an output has, or how to read a specific output like depth, normals, albedo, or distance.
Cloning USD subtrees to create copies at new paths. Use when user asks to clone, duplicate, copy a prim, or create instances of existing geometry.

Use this skill when the user asks to assign lidar/radar/acoustic material semantics, choose nonvisual base materials, coatings, or attributes, debug material IDs, or bind sensor-facing USD materials.
Resolve inputs in this order: existing repository files and referenced snippets, explicit user request, then broader agent context.

Non-visual material labels let lidar, radar, and acoustic sensors map USD materials to sensor-return behavior. The visual MDL material can stay ordinary; the sensor semantics come from custom material attributes that encode a base material, coating, and optional attributes into a material ID.

Author the labels on the Material prim that geometry binds with rel material:binding. The base material is required. Coating and attributes are optional; use none for unlabeled surfaces.
The default runtime prefix is omni:simready:nonvisual. The alternate supported prefix is inputs:nonvisual, selected by /rtx/materialDb/nonVisualMaterialSemantics/prefix. Public examples may write both prefixes so scenes work with either setting.
Use these exact base material strings.

none and calibration_lambertian map to DefaultMaterial behavior. Other base materials default to CompositeMaterial behavior.

|---|---|---|
none | 0 | Default, unlabeled, or unspecified coating. |

Attributes are encoded as a bit field, so multiple attributes can be combined when the USD representation supports a list.
| Attribute | Index | Use |
|---|---|---|
none | 0 | Unspecified attribute. |
emissive | 1 | Energy-emitting surface. |
retroreflective | 2 | Retroreflective surface. |

visually_transparent | 8 | Material is visually transparent. |

The material system can map material IDs to these BSDF behavior types: Constant, DefaultMaterial, CoreMaterial, AcousticMaterial, CompositeMaterial, RetroReflectiveMaterial, and ValidationMaterial.
Use behavior remapping settings only when a sensor model needs a non-default BSDF behavior for a material ID.
