Редактирование

After unwrap, you will likely need to arrange the UV maps, so that they can be used in texturing or painting. Your goals for editing are:

• Stitch pieces (of UV maps) back together.

• Minimize wasted space in the image.

• Enlarge the faces where you want more detail.

• Re-size/enlarge the faces that are stretched.

• Shrink the faces that are too grainy and have too much detail.

With a minimum of dead space, the most pixels can be dedicated to giving the maximum detail and fineness to the UV texture. A UV face can be as small as a pixel (the little dots that make up an image) or as large as an entire image. You probably want to make major adjustments first, and then tweak the layout.

Blender offers several ways of mapping UVs.

The more advanced methods can be used with more complex models, and have more specific uses.

UV ‣ Pin/Unpin

Горячая клавиша:

P, Alt-P

You can pin UVs so they do not move between multiple unwrap operations. When Unwrapping a model it is sometimes useful to «Lock» certain UVs, so that parts of a UV layout stay the same shape, and/or in the same place. Pinning is done by selecting a UV, then selecting Pin from the UVs menu, or the shortcut P. You can Unpin a UV with the shortcut Alt-P.

Pinning is most effective when using the Unwrap method of UV mapping, for organic objects. An example is when you are modeling a symmetrical object using the Mirror Modifier. Some of the UVs on the mirror axis may be shared across the mirrored counterparts. You could pin the UVs that correspond to the midline, then align them on the X axis, and they will stay in that location.

The sculpting tools, Pinch and Relax, will not move any pinned UVs. This allows you to pin the borders, or around interior holes, and gives even more control to the sculpt tools.

Pinning also works great with the Live Unwrap tool. If you pin two or more UVs, with Live Unwrap on, moving or scaling the pinned UVs will interactively unwrap the model. You can even use the Grab sculpting tool to move the pinned UVs. This helps with fitting a UV island to a certain shape or region.

Pack Islands

Режим:

Режим редактирования (edit mode)

Меню:

UV ‣ Pack Islands

The Pack Islands tool can be used to optimize the UV layout by adjusting existing islands to efficiently fill the Texture Space. Based on the options selected, the tool will scale, translate and rotate the islands, ensuring a specified margin exists between them to maximize the usage of the UV space. Pinned islands can have additional restrictions applied to customize the packing process even further.

Shape Method

The method to use when considering the shape of each island.

Exact Shape (Concave):

Use the complete shape of the island, including filling any holes or concave regions around the island.

Boundary Shape (Convex):

Takes into account the boundary (Convex Hull) of the island. This method will not place islands inside holes.

Bounding Box (габаритный контейнер):

Uses the simple bounding box of the island.

Масштаб (scale)

Scale the islands to fill the unit square, or pack islands towards the lower left corner.

Вращать (rotate)

Allows the rotation of islands, as well as translation and scaling, to optimize texture usage.

Rotation Method

The allowable rotations to use for each each island.

Any:

Any rotation which improves the packing is allowed.

Axis-aligned:

The island will first be rotated into a smallest rectangle. Additional rotation will only be in 90-degree turns.

Кардинальный сплайн (cardinal):

Like the four cardinal directions on a compass, North, South, East and West, only 90-degree turns will be allowed.

Margin Method

The method to use when calculating the empty space between islands.

Scaled:

Use scale of existing UVs to multiply margin.

Добавить (add):

Simple method, just add the margin.

Фракция:

Precisely specify the fraction of the UV unit square for margin. (Slower than other two methods.)

Отступ (margin)

The scale for the empty space between islands.

Lock Pinned Islands

An island which has any of its UVs pinned is considered a Pinned Island. With this option, Pinned Islands will be unable to move. The other islands will pack around them.

Lock Method

Change the way Pinned Islands are packed

Масштаб (scale):

The scale of the Pinned Islands will not change.

Вращение (rotation):

Pinned Islands will not rotate.

Вращение и масштаб:

Pinned Islands can translate, but not scale nor rotate.

Merge Overlapping

Before the main packing operation, overlapping islands are detected and temporarily combined. During packing, the relative rotation and position of the merged islands are preserved.

Pack To

Determines the final placement of UV islands after completing the packing operation.

Closest UDIM:

Pack islands to the UDIM grid nearest to the center of the selection.

Active UDIM:

Pack islands to the active UDIM image tile or, if no image is available, the UDIM grid tile where the 2D cursor is located.

Original bounding box:

Find the original bounding box of the selection, packs the islands, and then moves them back inside the original box.

Примечание

The performance of the Pack Islands operator is heavily affected by the options selected, and sometimes the options can combine in different ways to produce unexpectedly slower results.

The fastest results can be obtained by using the «Bounding Box» shape method and the «Add» margin method.

Although enabling the «Rotate» option slightly impacts performance, it will often enhance efficiency, making it a good choice to always keep enabled.

However the «Fraction» margin method requires significantly more computation to find the exact scale. For certain layouts, it may even take up to 10 times longer to complete then using the simpler «Add» or «Scaled» methods.

Similarly, the «Exact shape» and «Boundary shape» methods are much slower than the simple «Bounding Box» method.

The Minimize Stretch tool, reduces UV stretch by minimizing the difference between the angles in 3D and the angles in UV space. This operation is similar to the Relax tool with the Geometry Relaxation Method, but uses a different algorithm.

Fill Holes (Заполнить отверстия)

Just during minimize stretch, internal holes will be filled with temporary polygons to prevent stretching and overlaps of the surrounding UVs.

Смешать

The fraction between 0 and 1 of the original UVs to blend in once the stretch is minimized. A blend of 0 is the fully minimized stretch. Blend of 0.5 is halfway between the original UVs and the minimize stretch UVs.

More iterations result in smoother UVs, but take longer to process.

The Align Rotation tool aligns entire islands to either the U or V axis.

The tool has three different methods of operation. The different methods specify the source for the alignment, and also whether to align with both the U and V axes, or just the V axis alone.

When using the Auto method, islands are aligned so that UV edges are aligned to either the U axis or the V axis. This method works best with quads and meshes representing organic subjects.

When using the Edge method, only the selected edges are considered, and the islands will be aligned such that the selected edges are aligned with the V axis. This method works with the selection, so it works best when a particular edge, or edge loop, needs to be aligned in UV coordinates.

When using the Geometry method, the geometry is taken into consideration. Either the X axis, the Y axis, or the Z axis can be used. Suppose the X axis is chosen. Using this method, edges which have a positive extent in the X axis will be rotated in the UV map so that the edge extends upwards in the V axis. This method works best to align multiple islands which share some common geometric property, either in the X, Y or Z axis.

Note that in the Auto method, edges can end up aligned either up or down or left or right depending on the orientation of the island prior to activating the tool. In the Edge method, the alignment of selected edges can be either up or down in the V axis, whatever is closest to the current orientation of the UV island. By comparison, in the Geometry method, the alignment will always be pointing up in the V axis, ignoring any previous orientation.

For example, if a triangle attached to a quad attached to a quad is in the clipboard, then a different triangle <=> quad <=> quad is selected, then the topologies match, and the UVs will be pasted over the current selection.

For best results, you may want to use the Rip tool, or UV > Split > Selection, prior to using Paste UVs.
