This plugin extends Unreal Engine capabilities by adding runtime Assets loading (Static and Skeletal Meshes, Curve and Skeletal-based Animations, Materials, Textures) from standard glTF Files.
Assets can be loaded from filesystem, HTTP servers, or built from JSON strings.
The main goal is to allow project graphics modding, but can be used in any scenario requiring you to load/view/manipulate assets after the game has been packaged.
GLTF 2.0 (Embedded and Binary) is supported.
In addition to Runtime, Assets can be loaded in Editor too for simplifying testing and fixing.
Functions (both Blueprint and C++) for modifying Assets structures (like bone hierarchy) are included.
The Project is fully open source (MIT License), but it is available in the Epic Marketplace too, allowing users to sponsor the project by buying ready-to-use packages.
