| - | == Density == | + | === Density |
| Density is the parameter controlled by the slider in the simple mesh controls dialog. It uses a formula to control how close the polygon edges are to the original surface. The default value is 0.5, and acceptable values are between 0 and 1. Larger values result in a mesh with a higher polygon count.\\ {{: | Density is the parameter controlled by the slider in the simple mesh controls dialog.
