What are the top tips for simplify environment 3D models?

To simplify environment 3D models, focus on cutting polygon count, optimizing textures, and removing non-essential details—all while preserving the core visual identity. Use decimation tools (like Blender’s Decimate modifier) or level-of-detail (LOD) systems to lower polygons (critical for real-time performance in games/virtual tours). Merge textures into atlases or downsize them to reduce memory use. Strip tiny, unnoticeable elements (e.g., small rocks, trim) that don’t impact the environment’s look. For beginners, try built-in tools (Unity’s LOD Group) and adjust settings gradually—balance quality and performance without losing the environment’s character.
