Each of the Merge tools adds a preprocessing step to the optimization process. These can help correct specific problems in a model.

Interface

Merge Vertices

When on, merges vertices before performing the optimization. Default=off.

ThresholdSets the distance within which vertices are merged. This distance is based on a percentage of the size of the object’s bounding box. At the Threshold value of 0.0, the distance is about 0.0001 percent of the bounding-box size. At the Threshold value of 100.0, the distance is about 5 percent of the bounding-box size. Range=0.0 to 100.0. Default=0.0.

Merge Faces

When on, merges coplanar (or nearly coplanar) faces before performing the optimization. Default=off.

WarningIf the planar surface has holes in it, Merge Faces might not give correct results. Also, if the planar surface has repeated (tiled) UV mapping, the tiling information will be lost.

Threshold AngleSets the angle between face normals within which faces are merged. Range=0.0 to 10.0. Default=0.0.

Original model

Vertices: 557

Merge Faces turned off

Vertex % = 25.0

Vertices: 139

Faces: 214

Merge Faces turned on

Vertex % = 25.0

Vertices: 23

Faces: 21

When a model has coplanar faces, Merge Faces can greatly improve optimization.
