A real-time 3D game engine increasingly used directly for high-end architectural visualization and VR, the underlying technology Twinmotion itself is built on. Twinmotion trades some of Unreal's raw flexibility for a much faster, AEC-tailored workflow - a studio that needs full creative control over lighting, materials, and interactivity beyond what Twinmotion's simplified interface offers will often go straight to Unreal itself instead.
