Reduce Vertex Count

The ReduceMesh command decreases the polygon mesh face count while minimizing geometric and texture distortion.

Note

The mesh is first triangulated, its polygon count is reduced, and the resulting triangular mesh is quadrangulated again.
Nonmanifold meshes (meshes whose edges are shared by more than two faces) may produce undesirable results in some cases.

Steps

Select mesh objects.
Set the mesh reducing options.

Reduce Mesh Options

Starting polygon count

The number of triangle polygons. Every quadrangle face is counted as two triangle polygons.

Reduce to ___ polygons

Specifies the desired number of polygons.

Reduce by ___ percent

Specifies reduction by a percentage of the starting polygon count.

Planar only

Restricts reduction to planar polygons.

Locked mesh points

Reduce mesh command lets you lock mesh points. Reduction will not alter those points.

Show

Highlights locked mesh points.

Add

Adds selected mesh points into the set of locked mesh points.

You can use SelBrush to select and deselect points to add.

Remove

Removes selected from the set of locked mesh points.

Undo

Undoes previous operations.

Add all naked

Add mesh points on naked mesh edges into the set of locked mesh points.

Command-line options
Accuracy	1=Fast Trades accuracy for speed during conversion. Reduction is performed more randomly, involving fewer calculations, and is therefore faster. 10=Accurate Produces the fewest visible artifacts. This involves more calculations and is therefore slower. Note: This option does not affect the dialog version. The dialog version always uses 10 for max accuracy.
