How to optimize unity assets 3D models for students?

When optimizing Unity assets 3D models for students, prioritize reducing polygon count and simplifying textures to ensure smooth performance on common devices like laptops or tablets. Use Unity’s Mesh Simplifier or LOD (Level of Detail) tools to lower poly counts without losing key details—this helps avoid lag during project work. Resize textures to 1024x1024 or smaller to cut file size without compromising visual quality. For beginners, start with simple steps: delete unused vertices, merge small meshes, or remove hidden faces. This lets them learn gradually without frustration, before moving to advanced optimization tools.
