Modeling

Connected Geometry

Checks mesh objects for disconnected geometry components and stray vertices, edges, or faces that are separate from the object's primary mesh body.

Warning Fix: Yes Settings: Yes

Correct Normals Direction

Checks mesh objects for faces whose normals disagree with Blender's recalculated face orientation.

Critical Fix: Yes Settings: No

Location Applied

Checks mesh objects whose normal Location is not zero. The automatic fix strategy is configurable: preserve the current origin/pivot by moving Location into Delta Location, use Blender's native Apply Location behavior, or require a manual fix. Animated or driver-controlled Location is protected from being overwritten under Preserve Pivot mode; this protection does not currently apply under Native Apply Location mode.

Warning Fix: Yes Settings: Yes

Manifold Mesh

Checks whether mesh topology is manifold: each surface edge should belong to exactly two faces, with no boundary or non-manifold edges. Loose geometry is handled separately by the Connected Geometry check.

Critical Fix: No Settings: No

No N-Gons

Checks mesh objects for N-gons: polygons with five or more sides.

Critical Fix: No Settings: No

Rotation Applied

Checks if an Object's Rotation is applied (zero rotation in its active rotation mode — Euler, Quaternion, or Axis Angle). When fixed, resets rotation back to identity in Object Mode while permanently baking the object's current physical orientation into the mesh data.

Warning Fix: Yes Settings: No

Scale Applied

Checks if an Object's Scale is applied (1.0 on all axes). When fixed, resets scale to 1.0 in the sidebar while keeping the object's current visual size — its scale is baked directly into the mesh data instead.

Critical Fix: Yes Settings: No

Unique Edges

Checks for duplicate edges - two or more edges connecting the exact same pair of vertices.

Warning Fix: Yes Settings: No

Unique Faces

Checks for duplicate faces that use the same vertices. By default this also includes duplicates with reversed winding (opposite normals); that behavior can be disabled to allow intentional double-sided geometry such as foliage cards.

Warning Fix: Yes Settings: Yes

Unique Vertices

Checks for overlapping/duplicate vertices (multiple vertices sharing nearly the same position within a configurable tolerance).

Warning Fix: No Settings: Yes
