Vertex merging automatically detects and consolidates these redundant vertices, reducing data size without altering the model's visual appearance. This step alone typically achieves 10%-30% file size reduction.\u003C\u002Fp>\n\u003Ch3>Triangle Decimation\u003C\u002Fh3>\n\u003Cp>Proportionally reduce the number of triangles while preserving the model's overall shape.

Texture compression lets you downscale to lower resolutions (e.g., 1024×1024 or 512×512), dramatically reducing file size while maintaining near-identical visual quality at normal viewing
