USD UV Texture. Represents a standard USD primitive for looking up texture values. UV Coords. Returns texture coordinates or geometric s and t, depending on what is defined.

UsdUvTexture: Reads a source UV texture. UsdPrimvarReader: Reads and evaluates primvars. UsdTransform2D: Takes a 2D input and applies an affine transformation to it. Useful for transforming 2D texture coordinates. See Working with Primvars for a simple example that renders a texture.

The goal of this proposal is to have a preview material with a basic set of nodes that can be used to interchange assets from one platform to another in film and game pipelines, and which are supported natively by the production renderers that ship with USD/Hydra.

This package includes a set of libraries designed to support the use of USD in C#, as well as code to import and export USD files into the editor. The goal of this package is to make it maximally easy to integrate and explore Universal Scene Description.

3 days ago · USD files typically represent the scene as a hierarchy of primitives, or prims. Individual prims contain data to describe scene entities, such as geometry, lights, cameras and transform hierarchies. Blender’s USD importer converts USD …

We create the scene as a simple Model, add geometry and a Material with a simple shading network into the model, then bind the geometry to the Material. To fully illustrate these concepts, we walk through a Python script that performs the steps using the USD Python API, as well as showing the resulting text .usda outputs.

Apr 16, 2025 · MDL Identifier: UsdUVTexture. Description: Node that can be used to read UV textures, including tiled textures such as Mari UDIM’s.

Jul 13, 2023 · Create a project, making use of USD specific features, such as choice of scope and variants, subdivison levels and animation frames. Export materials and textures using the USD format. Additionally, USD had been added as a new file format for mesh-only export.

This node lets you tranform the texture coordinates on USD primitives, interactively in the viewport or with parameters. Internally, this node imports the USD geometry into SOPs, applies a UV Transform node, and then applies the modified attributes back onto the USD prims as overrides.

Nov 22, 2021 · I tried installing the newest version of the Autodesk USD exporter Version 0.14.0. When I re-export the model to USD, the texture attribute is now called "uv" instead of "map1", but the uv attribute is a 3d float array instead of a Vector2.
