forge-scene-loading

To render glTF scenes with multiple materials in SDL3 GPU, use forge_gltf_load() to parse JSON and binary data, then bind per-primitive uniforms and fragment shaders for multi-material rendering.

SDL3 GPU supports indexed rendering for glTF scene graphs by setting up vertex and index buffers, traversing parent-child transforms, and rendering with SDL_DrawGPUIndexedPrimitives.

You can bind textures and solid colors in a single draw call by uploading textures, creating samplers, and binding material data as per-primitive uniforms during the fragment shading stage.

You need forge_gltf_load(), cJSON for parsing, and SDL_GPU APIs to upload buffers and render glTF 2.0 scenes with proper transforms, textures, and scene graph hierarchies.

You can build and traverse parent-child transforms to render complex glTF model hierarchies by loading the scene graph and applying the transforms during the indexed rendering pipeline setup.

glTF multi-material meshes may not render correctly if vertex and index buffers are not properly uploaded, or if material data, textures, and samplers are not bound during SDL_DrawGPUIndexedPrimitives.
