Smoothing Algorithm
None (Fast)
Linear Interpolation
Cubic (Best)
Catmull-Rom Spline
Better smoothing = finer output but slower
Detail Level
1.0x
0.5 = smooth | 1.0 = normal | 2.0 = sharp
Mesh Subdivision
None (Fast)
Level 1 (Balanced)
Level 2 (Fine)
Level 3 (Ultra Fine)
Higher = smoother mesh but larger file
Smoothing Iterations
1
More iterations = smoother but may lose detail
Enable Mesh Optimization (recommended)
Adaptive Mesh (more triangles in detail areas)
