Mesh Simplification

Settings to generate optimized meshes.

Simplify Mesh by Slope should be enabled unless for specific reasons. If enabled, vertex density will be adjusted by the slope of the segment. Therefore, surfaces with dramatic slope changes will have more triangles.

Segments that have a slope higher than the Slope Threshold will not be combined with the adjacent segments. Therefore, decreasing this value will generate higher poly meshes.

Max Number of Segments to Combine value is the maximum number of segments that can be combined with the adjacent segments along X and Z axes. This is useful to avoid large flat surfaces when the slope threshold is high.

• Slope Threshold: 0.25.
• Max Number of Segments to Combine: 32.
