OutlineLine Color – Specifies the color of the outlines. If a texture is selected, it overrides the color as long as the texture checkbox is enabled. See the Lines Color example below. Opacity – Specifies how transparent or opaque the outlines are. A texture map can be used for this channel. Normal Threshold – Determines when lines will be created for parts of the same object with varying surface normals (e.g. at the inside edges of a box). A value of 0.0 means that only 90 degrees or larger angles generate internal lines. Higher values mean that smoother transitions between face normals can also generate a line. Setting this value to 1.0 fills curved objects completely. Overlap Threshold – Determines when outlines will be created for overlapping parts of the one and the same object . Lower values reduce the internal overlapping lines, while higher values produce more overlap lines. Setting this value to 1.0 fills curved objects completely. Width – Specifies the width of the outlines. See the Line Width example below. |
