In the following table, you will find property descriptions for each of the settings in the Skeletal Mesh Reduction Tool:

Property

Definition

Termination Criterion

The method to use when optimizing the Skeletal Mesh LOD. Available options are Triangles, Vertices First Percent Satisfied, Max Triangles, Max Vertices, First Max Satisfied.

Percent of Triangles

The percentage of triangle to retain as a ratio, eg. 0.1 indicates 10 percent.

Percent of Vertices

The percentage of vertices to retain as a ratio, eg. 0.1 indicates 10 percent.

First Percent Satisfied

Simplification will continue until either Triangle or Vertex count criteria is met.

Max Triangles

The maximum number of triangles to retain.

Max Vertices

The maximum number of vertices to retain.

First Max

Simplification will continue until either Triangle or Vertex count criteria is met.

Remap Morph Targets

Remap the morph targets from the base LOD onto the reduced LOD.

Max Bones Influence

Maximum number of bones that can assigned to each vertex.

Enforce Bone Boundaries

Penalize edge collapse between vertices that have different major bones. This will help articulated segments like tongues but can lead to undesirable results under extreme simplification.

Volumetric Correction

Default value of 1 attempts to preserve volume. Smaller values will lose volume by flattening curved surface, and larger values will accentuate curved surfaces.

Lock Mesh Edges

Preserve cuts in the mesh surface by locking vertices in place. Increases the quality of the simplified mesh at edges at the cost of more triangles.

Base LOD

Base LOD index to generate this LOD. By default, we generate from LOD 0.

Welcome to the new Unreal Engine 4 Documentation site!

We're working on lots of new features including a feedback system so you can tell us how we are doing. It's not quite ready for use in the wild yet, so head over to the Documentation Feedback forum to tell us about this page or call out any issues you are encountering in the meantime.

We'll be sure to let you know when the new system is up and running.
