LWO
Extensions: lwo2 tools
LWO is the native object format for LightWave 3D, with a deep history in the visual effects industry. It can store meshes, materials, textures, and animation data. LightWave users commonly use this format when exchanging assets between characters and scenes.
LWO's ecosystem is limited to the LightWave user base, and modern mainstream engines and web tools have limited support for it. Cross-software usage often requires conversion. If assets need to be used in Unity/Unreal or a browser, it is recommended to first convert to GLB or OBJ.
