Mesh Simplification

Target (faces)

Number of faces in the optimized mesh.

Erase Source

Delete the source mesh or not.

Boundary Weight

The coefficient that determines the degree of identity of the edge before and after mesh simplification.

The parameter values range from 0 to the infinity. The more the value is, the more detailed the mesh will be on its boundaries, and the less will be the deviation of edge of the optimized mesh from its previous position. When the value = 0, the mesh boundary looks “ragged”, the mesh edge is rough. Too large value would lead to excessive detailing of the mesh edge and increased optimization time.

Optimal value = 1.

Preserve Topology

Allows you to create a mesh without self-intersections of faces, which may occur as a result of its optimization. The parameter value should always be Yes.

Generate Normals

Whether to create vertex-by-vertex normals. It is used for improved display of a mesh.

The default value is Yes.

Face Quality

Whether to strive to create a mesh with faces close to equilateral triangles.

When the option is disabled, narrow faces with very long edges can be created.

The default value is Yes.

Ignore Texture

Optimizes a mesh without saving its texture, if any. The default value is Yes.

In most cases the option should be enabled, i.e. a mesh should be optimized without saving its texture. In this case the existing texture will be distorted, therefore, at the end of optimization, to re-overlay texture use the Texture Atlas Overlay command.

Optimization in the texture saving mode is performed with less quality, than in ignoring mode. It makes sense to optimize a mesh with saving texture in such rare cases, when you need to have texture on the mesh, but it is not possible to restore the texture by point cloud (for example, there is no point cloud by which the mesh was created).
