glTF

glTF files can be used in the 3D Layer and the Trip Layer in Studio.

Studio supports glTF files as follows:

glTF v2 files
glTF v1 files are supported on a best effort basis, but are not guaranteed to work.
A subset of glTF extensions are supported, see table below.

While all supported glTF files will load and render in Studio, the following rendering features are not supported:

morph targets, joints and skins
order independent transparency (rendering artifacts for transparent materials).

Note: simple (scene graph) animations and basic transparency are supported.

glTF Extensions

The glTF format evolves by adding optional extensions to the specification.

The following glTF extensions are currently supported by Studio:

glTF extension	Description
`KHR_draco_mesh_compression`.	Compressed mesh attributes (geometry).
`KHR_materials_unlit`	Specifies that a material should not be affected by light. Useful for pre-lit materials (e.g. photogrammetry).

Most glTF extensions are optional, so even if a glTF file contains an extension that is not supported by the Studio Platform, the Studio application will still be able load and display the file.

It is however possible for a glTF file to mark an extension as required, in this case Studio may fail to load it if the extension is not supported.
