When a 3D eye model looks ugly in ZBrush, it’s usually due to poor topology flow, incorrect UV unwrapping, or mismatched material/texture settings.
- **Topology**: If it doesn’t follow the eye’s natural curves (like eyelids or iris), details get distorted. - **UVs**: Bad unwrapping causes textures to stretch or blur, losing definition. - **Materials/Textures**: Missing subsurface scattering (for eye translucency) or low-quality textures (e.g., flat irises) make eyes seem unrealistic.
To fix it, refine topology to match eye contours first, re-unwrap UVs for even texture distribution, and test materials with subtle subsurface scattering—start with ZBrush’s default eye materials as a simple base.
