How UV Weld works

UV 焊接是如何工作的

UV Weld

紫外线焊接

This command required an active selection: UV components must be selected along UV Seams. The selected elements must build a connected mesh, whose UV mesh is unstitched, on the 3D object. You cannot, for example, connect the UV polygons of a character’s foot with those of the character’s eyes but you can connect those of the foot with those of the ankle if these were separated in the UV mesh. these separated UV Islands can later be re-attached at the fitting location.

这个命令需要一个主动选择: 紫外线组件必须沿着紫外线接缝选择。选择的元素必须建立一个连接的网格，其紫外线网格是未缝合，在3D 对象。例如，你不能把角色脚上的紫外线多边形和角色眼睛上的多边形连接起来，但是如果这些多边形在紫外线网格中被分开的话，你可以把脚上的多边形和脚踝的多边形连接起来。这些分离的紫外线岛屿可以稍后在适当的位置重新连接。

This can differ somewhat, depending on the component mode selected:

这可能有些不同，取决于选择的组件模式:

• In Use Point mode, the UV points of opposite seams must be selected on both sides. Corresponding points will be welded midway between the two respective points. 在使用点模式，相反的接缝的 UV 点必须在两边选择。相应的点将焊接在两个相应点之间的中途
• In Use Edge mode, only one side of the edges has to be selected to connect them with the corresponding UV edges. Corresponding UV points will be welded midway between the two respective points - looks like Use Point mode in the above image if the same selection is made. 在使用边缘模式，只有一边的优势，必须选择连接他们与相应的 UV 边缘。相应的紫外线点将焊接在两个相应的点之间的中途-看起来像使用点模式在上面的图像，如果相同的选择
• In Use Polygon mode, all selected polygons - if they are connected to the border polygons - will be connected to the opposite side and a relaxation will take place concomitantly. Contrary to UV point selection, you only have to select UV seam polygons on one side. The algorithm will then connect the corresponding polygons automatically. 在使用多边形模式下，所有选定的多边形——如果它们连接到边界多边形——将同时连接到对面，并放宽限制。与 UV 点选择相反，你只需要在一边选择 UV 接缝多边形。然后，该算法将自动连接相应的多边形

All components can be selected in any mode to automatically weld corresponding components to other UV seams.

所有部件可以选择在任何模式，自动焊接相应的组件到其他紫外线接缝。

Make sure that the regions to be connected lie close to one another in the UV mesh because the resulting mesh will otherwise crisscross.

确保要连接的区域在 UV 网格中彼此靠近，因为生成的网格会交叉。

Note also the UV Weld and Relax... command that at first works like UV Weld but also relaxes and realigns the mesh.

还要注意 UV 焊接和放松... 命令，在第一个工程像 UV 焊接，但也放松和重新调整网格。

UV Weld and Relax...

紫外线焊接和放松..。

General

常规

This command can be used to re-attach separated UV meshes and Islands, which is similar to what the UV Weld command does. As the name suggests, the UV Weld and Relax command goes further: The UV mesh will also be relaxed after being welded (using ABF relaxing) and subsequently realigned.

这个命令可以用来重新附加分离的 UV 网格和岛屿，这是类似的 UV 焊接命令所做的。顾名思义，紫外线焊接和放松命令走得更远: 紫外线网格也将放松后被焊接(使用 ABF 放松) ，随后重新调整。

The default state when the command is called up is UV component selections, which are elements of UV Seams as described here for the UV Weld command (the weld process works for the most part as it does there).

当命令被调用时的默认状态是 UV 组件选择，这是 UV 接缝的元素，正如这里所描述的 UV Weld 命令(焊接过程的大部分工作，因为它在那里)。

In the next step, the mesh relaxation, UV Pins will be included, which affix UV points at the location at which they lie. If the next step - realigning (Auto Realign enabled) - the UV Pins will no longer apply. Don’t be surprised if the UV Pins move as a whole.

在下一步，网格松弛，UV 引脚将包括在内，这将贴上 UV 点的位置，他们躺在。如果下一步-重新调整(自动重新调整启用)-紫外线引脚将不再适用。不要惊讶，如果紫外线针作为一个整体移动。

What can the result look like?

结果会是怎样的呢？

In the top half of the image above, two UV polygon rows were selected (could have also been edge selections or point selections on both sides of the seam), with which the command attaches the island at the right location and/or closes a cut.

在上面图像的上半部分，选择了两个紫外线多边形行(也可能是边缘选择或接缝两侧的点选择) ，命令在正确的位置附加岛和/或关闭切割。

In the bottom half of the image, a UV Seam edge is selected and used to cleanly weld and realign both dinosaur head halves.

在图像的下半部分，选择一个 UV Seam 边缘，用于清洁地焊接和重新排列两个恐龙头部分。

Note also the UV Weld command that works similarly but does not relax or realign.

还要注意 UV Weld 命令的工作方式类似，但不会松弛或重新排列。

Calling up this command can produce an error message if UV meshes without seams are found (see also here).

调用这个命令可以产生一个错误信息，如果没有接缝的 UV 网格被发现(也看这里)。

Settings

设置

Use Polygon Selection

使用多边形选择

If this option is enabled, the effect will be restricted to existing polygon selections. Contiguous selections will be turned into new UV Islands.

如果启用此选项，则效果将局限于现有的多边形选择。连续选择将变成新的 UV 岛屿。

Pin Point Selection

点选择

UV points affixed via UV Pins will remain unchanged if this option is enabled and Auto Realign in disabled. The command will remain restricted to the mouse’s tail, which is welded to the body via polygon selection.

如果启用这个选项并且禁用自动重新调整，通过紫外线钉固定的紫外线点将保持不变。该命令将继续限制在鼠标的尾巴，这是焊接到身体通过多边形选择。

If you want to affix certain UV points only for the relaxing process, select the respective points and call up the Add UV Pins command. Note that if Auto Realign is enabled, these points can move after the relaxing process has been concluded.

如果你只想在放松过程中添加某些 UV 点，选择相应的点并调用 Add UV Pins 命令。请注意，如果自动重新调整启用，这些点可以移动后，放松过程已经结束。

Auto Realign

自动调整

Enable this option if the UV Islands should in the end cover the UV tile and be as free as possible of overlapping. You will use the Bounding Box mode, as you know it from the UV Manger’s UV Packing menu.

启用这个选项，如果紫外线岛屿应该在最后覆盖紫外线瓷砖，并尽可能免费的重叠。你将使用包围盒模式，因为你知道它从紫外线管理器的紫外线包装菜单。
