When exporting OBJ 3D models, prioritize optimizing geometry, linking MTL files correctly, matching settings to your use case, and bundling assets for sharing.
Optimize by deleting unused vertices or faces—this reduces file size, which is helpful for games or web previews. Link MTL files (which store texture/material info) with short, consistent paths (like "textures/wood.png") to ensure the model displays properly in other software. Adjust settings like coordinate systems (Y-up for Blender, Z-up for Maya) and enable normals for consistent shading across platforms.
Zip the OBJ with its MTL and textures when sharing—this prevents missing assets and makes collaboration smoother.
