Which statement about Unity file formats is true?

• A. Unity supports OBJ and FBX files.
• B. Unity only supports FBX files.
• C. Unity supports STL and OBJ files.
• D. Unity supports DAE and FBX files.

Answer: (A)

Models in Unity are brought in through the asset import pipeline, which supports several common 3D formats. FBX is widely used because it preserves geometry, textures, and animation data from many 3D applications, making it suitable for characters and complex props. OBJ is also supported and is excellent for static meshes; it includes geometry and can reference an MTL file for basic materials, though it doesn’t carry animation. The combination of FBX and OBJ covers common use cases for Unity imports. Formats like STL are designed for 3D printing and generally do not carry textures or animation in Unity, so they are not standard for Unity imports. DAE (Collada) has limited and less common support in modern Unity workflows, so it's not relied upon as a primary import format. Therefore, Unity supports both OBJ and FBX files.
