Native glTF & GLB Importer + Runtime

🚀 Introducing glTF Importer for Unity! 🚀

Drop a .gltf or .glb file into Unity and use it like any other model. No setup, no

external dependencies, no asking your players to install anything. It works in the

editor and at runtime, and it figures out your render pipeline for you.

Works perfectly with Unity 6, on Built-in, URP and HDRP!

🎯 Just Drag & Drop: Bring a .gltf or .glb into your project and Unity imports it

exactly like an FBX, a ready prefab with its meshes, materials, textures and

animations tucked inside. Edit the source file and it re-imports on its own. There

is nothing to configure to get started.

🧩 One Importer, Every Pipeline: The render pipeline is detected automatically and the matching shaders are used, so the same file looks right whether your project is Built-in, URP or HDRP. No manual material fixing after import.

⚙️ glTF Importer handles:

PBR metallic-roughness materials, plus unlit.

Albedo, normal, metallic-roughness, occlusion and emissive maps.

Embedded textures (inside the .glb) and external image files.

Older specular-glossiness materials, converted to metallic-roughness on import.

Skinned meshes, blend shapes and animation clips.

Cameras and lights.

Multiple UV sets, vertex colors and sparse accessors.

Extensions: KHR_materials_unlit, KHR_materials_pbrSpecularGlossiness,

KHR_texture_transform, KHR_materials_emissive_strength, KHR_lights_punctual,

KHR_mesh_quantization and KHR_draco_mesh_compression.

📦 Load at Runtime: Let players bring their own models, or stream content into a live game, with a powerful API:

using HyTeKGames.glTFImporter;

GameObject model = RuntimeGLTF.LoadModelAsGameObject(bytes);

GameObject fromDisk = RuntimeGLTF.LoadModelAsGameObject(path);

and more !

Load from a byte[] you already hold in memory,or straight from a file path. Ask for a full GameObject, a single mesh, or every mesh in the file.

🔍 Live 3D Preview: Click an imported model and rotate it right in the Inspector,

the way you would an FBX. A short PDF in the package covers the runtime methods.

🌐 Where it helps:

User-Generated Content: let players import their own props, vehicles or avatars at runtime.

Mixed-Pipeline Projects: ship the same assets to Built-in, URP and HDRP without

rebuilding materials.

Fast Iteration: skip the FBX round-trip and pull glTF straight from Bl*nder,

Subst*nce, Sketchf*b and the rest. (Trademarks hidden)

🧱 No Dependencies: The JSON reader is built in, so there is nothing extra to install.

(Draco-compressed geometry is the one exception, it uses Unity's free

com.unity.cloud.draco package when you need it.)
