DAE

DAE (COLLADA) is an open exchange format maintained by the Khronos Group. It uses XML to describe scene graphs, geometry, materials, textures, animations, and lights, aiming for lossless transfer of digital assets between different 3D authoring tools. Software such as Blender and Maya support COLLADA import and export.

The text-based structure of DAE makes its file sizes relatively large, and there are differences in COLLADA implementations across different software. Complex scenes may lose materials or animations when transferred between tools. In the context of real-time web rendering, the glTF family has replaced COLLADA as the mainstream, and DAE is more commonly used for interoperability in traditional DCC toolchains.
