Free tools for LOD (Level of Detail) prefabs include Blender (LOD generation), Unity’s built-in LOD Group, and Godot’s LOD system—all free and easy to use. - Blender: Use the "Decimate" modifier to make lower-poly LODs (manually or automatically) and export as prefabs. - Unity/Godot: Integrate LOD directly in-engine—assign levels to optimize real-time 3D scenes without extra tools. For beginners, start with Blender to simplify models, then use Unity/Godot to apply LOD—this cost-free workflow boosts performance without hassle.
