Reduce

Reduce lowers the polygon count of a mesh while preserving the overall shape. This is useful for simplifying highly detailed models, reducing file size, and speeding up operations on complex geometry.

How to Use

  1. Select an object
  2. Click Reduce in the Mesh group of the toolbar
  3. Choose Percent or Count and set the target

Parameters

  • Mode - How you set the target:
    • Percent (default) - Keep a percentage of the original polygons
    • Count - Aim for a number of polygons
  • Source Polygon Count - The original number of polygons (read only)
  • Target Count - The number of polygons to keep (shown in Count mode)
  • Target Percent - The percentage of polygons to keep (default 50; 1 to 100; shown in Percent mode)
  • Maintain Surface - Off by default. Keeps every reduced point on the surface of the original mesh. This is not normally needed and makes the reduction much slower
  • Final Count - The number of polygons the percentage gives (read only; shown in Percent mode)

Tips

  • 50% reduction usually preserves visual quality well
  • Enable Maintain Surface when accuracy matters more than speed
  • Reducing polygon count speeds up boolean operations on complex imported models
  • Very low polygon counts will visibly degrade the shape – check the result before committing
