Long name (short name)	Type	Default	Flags
percentage (p)	double	0
Percentage of triangles to be removed.
compactness (com)	double	0.0
Tolerance for compactness for the generated triangles A value of 0 will accept all triangles during decimation A value close to 0 will attempt to eliminate triangles that have collinear edges (zero area triangles) A value closer to 1 will attempt to eliminate triangles that are not strictly equilateral (of equal lengths) The closer to 1.0, the more expensive the computation
geomWeights (gwt)	double	1
How much consideration vertex positions are given in the reduction algorithm. A higher weight means the reduction will try harder to preserve geometry.
uvWeights (uwt)	double	0
How much consideration uv positions are given in the reduction algorithm. A higher weight means the reduction will try harder to preserve uv positions.
colorWeights (cwt)	double	0
How much consideration vertex color is given in the reduction algorithm. A higher weight means the reduction will try harder to preserve vertex coloring.
keepQuadsWeight (kqw)	double	0
How much consideration is given in the reduction algorithm to keeping quad faces. A higher weight means the reduction will try harder to keep quad faces and avoid creation of triangles.
weightCoefficient (wc)	double	10000.0
The weight of each vertex is multiplied with this coefficient when the reduction is performed. This value does not have to be edited, normally. It gives finer control over the weighted reduction.
weights (wts)	double	0
This attribute was used in 6.0 or earlier versions, and is not used anymore. This is an obsolete attribute.
vertexWeights (vwt)	doubleArray	empty
An array containing the weights of all vertices. A higher weight means that vertex is less likely to be reduced. If not specified, weights are assumed to be 0.
keepBorder (kb)	bool	true
Keep the object borders
keepMapBorder (kmb)	bool	true
Keep the object texture mapping borders
keepHardEdge (khe)	bool	true
Keep the hard edges on the object
keepOriginalVertices (kev)	bool	false
Keep original positions, UVs and colors of vertices when collapsing edges. If false, new vertices will be positioned to give optimal shape If true, the vertex closest to the optimal position will be preserved
triangulate (t)	bool	true
Triangulate all faces, included non reduced ones (for pre 5.0 files) For version 5.0, this attribute specifies if the geometry or the selected faces has to be triangulated, before performing reduction.
cachingReduce (cr)	bool	false
Cache intermediate reductions for speed at the expense of memory
border (b)	double	.5
Specifies the degree to which vertices along the geometric border are to be preserved. It has effect only if the keepBorder attribute is set to false. A value of 0 results in all border vertices being preserved. A value of 1.0 results in no special effort being made to preserve any border vertices.
line (l)	double	.5
Specifies the degree to which "feature lines" (edges joining faces with sharp geometric angles between them) are to be preserved. A value of 0 results in the greatest possible effort to preserve such features. A value of 1.0 results in no special effort being made to preserve such features.
detail (d)	double	.5
Specifies how much of the reduced geometry should be dedicated to preserving regions of high curvature. A value of 0 will concentrate the detail in areas of high curvature. A value of 1.0 will result in relatively equal distribution of vertices and faces regardless of curvature. This value is ignored when keepHardEdge is set to false.
