To fix weird issues (e.g., unnatural shapes, deformations, texture glitches) in creature 3D models, focus on four key areas: mesh topology, rigging, UVs, and sculpting.
- **Mesh topology**: Poor topology (ngons, overlapping vertices) causes deformations—clean by welding vertices or reducing ngons. - **Rigging**: Faulty bone weights or misaligned joints lead to weird movements—adjust weights via weight painting and test animations. - **UVs/textures**: Stretched UVs create glitches—check and fix unwrapping. - **Sculpting**: Smooth minor shape issues (like limbs or faces) with sculpting tools.
