How to fix sharp in trees 3D models?

To fix sharp edges in tree 3D models, use subdivision surfaces, edge weighting, or vertex normals—key methods to smooth edges without losing detail. - **Subdivision surfaces**: Add tiny polygons to round edges (ideal for leaves/bark, making them look natural). - **Edge weighting**: Keep important edges (like branch joints) sharp while softening others—balances smoothness and structure. - **Vertex normals**: Adjust light reflection to make edges look smoother, no mesh changes required. For Blender, use the Subdivision Surface modifier + edge creases (Ctrl+E > Mark Crease). For game engines, bake high-poly normals to a low-poly tree—fixes sharpness without performance issues.
