Free online USD to DAE converter

Source format: USD

USD usually refers to Universal Scene Description, a 3D scene description format developed by Pixar and widely used in animation, VFX, games, and digital content creation pipelines. It can store complex scenes with geometry, materials, lighting, animation, and references to other assets. USD is popular in collaborative production environments because it supports non-destructive scene composition and large-scale asset management.

Target format: DAE

DAE, also known as COLLADA, is an XML-based 3D interchange format used to move models and scenes between different 3D applications. It is commonly supported by modeling tools, game engines, and visualization software. DAE is useful when you need a broadly compatible exchange format for meshes, basic materials, skeletons, and animations, although support varies by application.

How to perform the conversion

The most reliable way to convert .usd to .dae is to use a 3D application or pipeline tool that can import USD and export COLLADA. A common workflow is:

1. Open the USD scene in a compatible 3D tool such as Blender, Autodesk Maya, or another application with USD support.
2. Check whether the scene loads correctly, including scale, units, materials, and animation.
3. Use the export function to save as COLLADA: File → Export → Collada (.dae) or the equivalent export menu in your software.
4. Choose export options for geometry, animation, and textures if needed, then save the file as output.dae.
5. If your software cannot export DAE directly, use an intermediate tool or pipeline step that supports both USD import and COLLADA export.

You can also convert the file on 101convert.com for free, without installing any software, if the built-in converter supports your specific USD variant.

Notes on quality and limitations

USD to DAE is often a lossy conversion. USD can represent advanced scene composition, variant sets, layered edits, and complex shading networks that COLLADA does not fully support. During conversion, you may lose materials, animation details, instancing, references, or USD-specific scene structure. DAE is best suited for simpler interchange of meshes and basic animation.

Compatibility also depends on the exact USD flavor you have, such as .usd, .usda, or .usdc. Some tools support only certain variants, and some USD scenes rely on external asset files that must be kept alongside the source. If textures or referenced assets are missing, the exported DAE may appear incomplete.
