Convert X (DirectX) to GLB Online — Legacy to Modern 3D

Skeletal animations are converted to glTF animation format. Simple animations (walk cycles, rotations) transfer well. Complex animation blending and procedural animations may not convert perfectly.

Basic material properties are mapped to glTF PBR metallic-roughness parameters. Diffuse color becomes base color with metallic=0, roughness=1. The result is a reasonable starting point that you can refine in a glTF editor.

Yes. GLB is the standard format for web 3D. Use Three.js, Babylon.js, Google model-viewer, or any glTF viewer to display the model. This is the recommended path for bringing legacy DirectX assets to the modern web.

Load with GLTFLoader: const loader = new THREE.GLTFLoader(); loader.load('model.glb', (gltf) => { scene.add(gltf.scene); }). Add proper lighting (DirectionalLight + AmbientLight or an environment map via RGBELoader) for best results. If the model looks flat or dark, it is a lighting issue, not a conversion problem. The geometry and materials from the X file are correctly embedded in the GLB.

X format uses external texture file references (relative paths). During conversion to GLB, referenced textures are embedded directly into the GLB binary container. If the texture files are not present in the same directory as the .x file during conversion, the GLB will have geometry but missing textures. Ensure texture files are co-located with the .x file before converting.
