When you reduce a 3D model, it often becomes invisible due to misconfigured Level of Detail (LOD) settings—like the smallest LOD level hiding the model instead of using a simpler version.
LOD optimizes performance by swapping to less detailed versions as the model shrinks. Common causes of invisibility include: - The tiniest LOD level having no visible mesh (e.g., accidental deletion). - Software automatically culling (hiding) objects below a minimum size. - Low-resolution textures that disappear when scaled down.
To fix: 1. Check your 3D tool’s LOD setup (e.g., Blender’s LOD modifier) to ensure all levels have visible meshes. 2. Disable automatic culling temporarily to test if that’s the issue.
