ufbx is a single source file FBX loader.

The library aims to provide a user-friendly interface to easily interpret the FBX file format while exhaustively supporting advanced features for those who need them.

  • Single C99/C++11 source file
  • Handles invalid files and out-of-memory conditions gracefully
  • Strongly typed API with bounds-checked slices in C++ and Rust bindings
  • Extensively tested and fuzzed

ufbx_load_opts opts = { 0 }; // Optional, pass NULL for defaults
ufbx_error error; // Optional, pass NULL if you don't care about errors
ufbx_scene *scene = ufbx_load_file("my_scene.fbx", &opts, &error);
if (!scene) {
    fprintf(stderr, "Failed to load: %s\n", error.description.data);
    exit(1);
}

// Use and inspect `scene`, it's just plain data!

// Let's just list all objects within the scene for example:
for (size_t i = 0; i < scene->nodes.count; i++) {
    ufbx_node *node = scene->nodes.data[i];
    if (node->is_root) continue;

    printf("Object: %s\n", node->name.data);
