Unwrap UV

打开紫外线

This new tool is at the core of an optimized edge workflow (edges defined as UV Seams, unwrapping/relaxing UV mesh with UV Unwrap, select more edges, unwrap again, etc.).

这个新工具是优化边缘工作流程的核心(边缘定义为 UV 接缝，展开/放松 UV 网格与 UV 展开，选择更多的边缘，展开，等等)。

UV Unwrap also works in conjunction with edge selections that are used as UV Seams. The UV mesh is opened and the edge selections, unwrapped, relaxed and re-arranged. This procedure might sound familiar to you. In principle, the same happens with the UV Relax command. UV Unwrap includes all of this in a single command, which makes the process much simpler and saves you a lot of clicks. The UV mesh relaxation is done using the ABF algorithm.

紫外线展开也工程与边缘选择，是用作紫外线接缝。UV 网格是打开和边缘的选择，打开，松弛和重新排列。这个过程你可能听起来很熟悉。原则上，UV Relax 命令也是如此。UV Unwrap 在一个单独的命令中包含了所有这些内容，这使得整个过程更加简单，并且节省了大量的单击。紫外光网格松弛采用 ABF 算法完成。

In Use Polygon mode, congruent selections will be seen as islands (and internally an edge selection will be placed around the islands) and unwrapped separately.

在使用多边形模式下，全等的选择将被视为岛屿(在内部边缘选择将被放置在岛屿周围) ，并解开单独包装。

Note that the command does not work with complete UV meshes that do not have a border, e.g., as can be the case with Shrink, Flat and Frontal projections on closed volumes. If, on the other hand, you only select a part of the mesh - which will then have borders - the algorithm will work.

注意，这个命令不适用于没有边框的完整 UV 网格，例如，在封闭体积上的收缩、平面和正面投影。另一方面，如果你只选择网格的一部分，那么这个算法就会起作用。

Tips and Tricks

技巧和窍门

• Good results can be achieved with organic objects if the original projection is done using Frontal, Flat or Shrink projection and then defining the UV Seams using edge selections. It can help to try out various projection types (e.g., different Frontal projections) to get the best results for UV Unwrap. 如果原始投影是使用正面、平面或收缩投影，然后使用边缘选择定义紫外线接缝，那么对于有机物体可以取得良好的效果。它可以帮助尝试不同的投影类型(例如，不同的正面投影) ，以获得最佳的结果为紫外线展开
• Imagine a T-Rex dinosaur, for example, (can be found in the Content Browser). Good results can be expected here if you first apply a Frontal projection, then define the edge seams and then unwrap the extremities individually: e.g., make an Edge Loop selection at the top of the left leg, then an edge selection from the loop at the back of the leg down to the foot, then branch out from the bottom of the feet to each toe and use this cut to help unwrap. Then you can turn to the right arm, for example and so on. 想象一下霸王龙，例如，(可以在内容浏览器中找到)。如果你首先使用正面投影，然后定义边缘接缝，然后单独打开四肢，可以得到很好的效果: 例如，在左腿的顶部做一个边缘循环选择，然后从腿后部的循环到脚部的边缘选择，然后从脚的底部到每个脚趾分叉，使用这个切口来帮助打开。然后你可以转向右臂，例如，等等

Settings

设置

The command has the following options:

该命令有以下选项:

• Use Polygon Selection 使用多边形选择: If a polygon selection exists, the algorithm will be restricted to this selection if this option is enabled. Otherwise the complete UV mesh will be edited (even if no polygons are selected). In Use Polygon mode, this option is grayed out. The polygon selection will be treated as a UV island - it will be separated from the rest of the UV mesh. : 如果存在多边形选择，如果启用此选项，则算法将局限于此选择。否则，完整的 UV 网格将被编辑(即使没有多边形被选择)。在使用多边形模式下，此选项为灰色。多边形选择将被视为一个紫外线岛-它将从紫外线网格的其余部分分离
• Add Pin Selection 添加引脚选择: Enable this option if points should be fixed to the UV surface for parts of the algorithm (see also : 启用此选项，如果点应该固定到 UV 表面的部分算法(参见Add Pin Selection 添加引脚选择). This fixation only applies to the internal relaxation step and not for the weld process or the final realignment (enabled Auto Realign) option. In the end, UV Pins will not stay put. An example of how the fixation process works for relaxation can be seen ).这种固定只适用于内部松弛步骤，而不适用于焊接过程或最后重新调整(启用自动重新调整)选项。最后，紫外线针将不会停留在原地。我们可以看到一个例子，说明这种注视过程是如何使人放松的here 这里.
• Auto Realign 自动调整: After the unwrapping and relaxing steps, the UV Islands involved will be aligned as efficiently and closely as possible in the UV Editor work area and, if possible, without any overlapping. Otherwise the new UV Islands will be stacked more-or-less over one another and will not lie within the assigned UV tile. : 在展开和放松步骤之后，所涉及的紫外线岛将在紫外线编辑工作区内尽可能有效和密切地对齐，如果可能的话，没有任何重叠。否则新的紫外线岛将堆叠或多或少相互之间，将不会在指定的紫外线瓦
