How to optimize fbx 3D models for game artists?

Game artists optimize FBX 3D models by reducing polygons, simplifying materials, and removing unused data to balance visual quality with game performance. Reduce polygons: Decimate high-poly models to low-poly while retaining key details—this lowers GPU load. Simplify materials: Merge textures into atlases or use efficient PBR workflows to cut draw calls. Clean data: Delete hidden faces, unused bones, or extra UV channels to shrink file sizes. This is key for mobile games (tighter hardware limits) or open-world titles (many models loading at once). For next steps, export to Unity/Unreal and use the engine’s performance profiler to check bottlenecks—adjust optimizations without over-simplifying.
