image support. 3.3 – September 2022 New hair object, procedural UV nodes, line art shadow and contour, Intel GPU rendering support via oneAPI, and improvements to library overrides. 3.4 – December 2022 Vertices are shown in black if they have no weight in any vertex group. Show Weight Contours Show contour lines formed by points with the same interpolated weight. This visualizes weight variations too Inner-Region, based on all regions currently selected, it selects only the edges at the border (contour) of these islands. It can operate in any select mode, but when in Face mode it will switch to Edge

Inner-Region, based on all regions currently selected, it selects only the edges at the border (contour) of these islands. It can operate in any select mode, but when in Face mode it will switch to Edge Overlapping Edges as Contour This option allows overlapping edges (e.g. from an Edge Split modifier or imported geometry where two edges occupy the exact same space) to be drawn as contour. Enabling this option of instanced objects in the scene. 截断区间 When enabled, line art will generate clipping lines as contour type at the place where near or far clipping planes cut the model. Otherwise there will be no lines

Inner-Region, based on all regions currently selected, it selects only the edges at the border (contour) of these islands. It can operate in any select mode, but when in Face mode it will switch to Edge cases.) ⾼级选项 Sphere Radius Affects the calculation of curvatures for Ridge, Valley and Suggestive Contour edge type selection in a line set. The curvature at each vertex is computed by averaging the shape threshold on the minimum rate of change of curvature used to filter the output of the Suggestive Contour edge type selection. Increasing the value reduces the amount of rendered lines, starting from smoother
