Smart Convert (Base)

Smart Convert is the recommended first action in Base 3.0. It analyzes the active mesh before choosing how aggressively to recover quads.

Mesh classification

Base distinguishes three broad cases:

• Hard surface: manufactured/CAD-style geometry where triangulation often hides recoverable quad structure.
• Scan / AI: dense triangulated surfaces where metadata such as UVs or marked sharp edges is not enough to call the mesh hard-surface.
• Mixed / organic: curved or irregular meshes that benefit from adaptive conversion rather than hard-surface diagonal recovery.

Hard-surface recovery

Hard-surface Smart Convert scores likely original triangle diagonals using local planarity, convex-quad validity, edge proportions, triangle area balance, seams, UV discontinuities, material boundaries, and real geometric creases. It pairs constrained triangles first so ambiguous early matches do not strand large triangle patches.

Mixed / organic conversion

Mixed and organic meshes use adaptive shape acceptance and bounded multi-pass conversion. This is still a conversion workflow, not a full retopology rebuild.

Result quality

• 90%+ quads: Strong result
• 70-90%: Usable mixed topology; residual triangles can be protected deliberately
• Below 70%: Partial conversion; inspect the remaining triangles or use a more suitable workflow

Do not chase 100% quads if the remaining pairs would create stretched or structurally incorrect faces.

When to move to Premium

If a dense scan, generated character, or organic mesh does not contain useful quad structure to recover, use Premium Production Rebuild. Base intentionally does not include the field-based reconstruction solver.
