Feature: FET_001_STANDARD

Property	Value
Feature Name	FET_001_STANDARD
Runtime	STANDARD
Proprietary Techs	None
Latest Version	1.0.1

Description

The Minimal Placeable Visual feature defines the standard OpenUSD contract for an asset that can be loaded, placed, transformed, and rendered as a visible object in a broad range of applications.

An asset that satisfies this feature has supported asset paths and file types, known stage units and up axis, a valid default prim, a single xformable root for placement, mesh-based visible geometry, authored extents, valid mesh topology, valid normals and winding, and an origin placement suitable for aggregation into scenes.

Dependency Graph

This feature has no JSON feature dependencies. In normal profile workflows it is validated after FET_000_STANDARD because Core establishes the asset layout, metadata, and path contract that Minimal builds on.

Use Cases

• Synthetic data generation and scene assembly.

• Robotics and simulation asset placement.

• Visual inspection of converted CAD, DCC, MJCF, or USD assets.

• Baseline renderability checks before physics, materials, grasp, robot, or runtime-specific features are applied.
