Sets the weld threshold: the radius within which welding using Weld Selected and Weld Selected Subobject (see preceding) take effect. Weld Any Match with Selected Combines a selected seam with its counterpart on another cluster without having to select the counterpart edges first.Weld All Selected Seams Combines any shared vertices and edges of all selected sub-objects the Threshold setting does not apply.Weld Selected Subobject Combines any shared vertices and edges of selected sub-objects within the current Threshold distance (see following).With Weld Any Match With Selected, only one of each pair need be selected. Note: Weld Selected Subobject and Weld All Selected Seams work alike in combining shared vertices and edges of selected sub-objects the difference is that Weld Selected Subobject works only within the specified Threshold distance, while Weld All Selected Seams works at any distance.Īlso, in both cases, each pair of sub-objects containing the shared vertices or edges must be selected. Thus it ensures that no cluster contains more than one material ID after flattening.īreaks up the texture polygons using the currentįlatten Settings (on Flatten: Custom flyout)įlatten Mapping dialog for specifying Flatten: Custom parameters. Flatten by Material IDīreaks up the texture polygons into clusters using only Material IDs. If some polygons have multiple smoothing group IDs, it's possible that the texture coordinates would not be able to be split into separate clusters. When flattening by smoothing group, in order to form a separate cluster, a group of polygons must be fully enclosed by hard edges that is, polygons that do not share any smoothing group IDs with their neighbors. Flatten by Smoothing Groupīreaks up the texture polygons using their With polygons, Break splits the selection off from the rest of the mesh into a new element.īreaks up the texture polygons using the following settings:įor explanations of the settings, see Flatten Mapping Dialog. With edges, Break requires at least two contiguous edges to be selected, and separates each edge into two. At the Vertex sub-object level, Break replaces each shared vertex with two vertices. In all other cases Stitch finds the best match, if the match is unselected, or stitches to the selected match.Īpplies to the current selection works differently in the three sub-object modes. If only one UV vertex is selected and it has more than one corresponding UV vertex, it will be stitched to the closest one. Also, with Show Vertex Connections on at the Vertex level, you can see exactly which vertices will be connected to which.Īlthough Stitch works only at the vertex and edge levels, it is available at all sub-object levels, and applies to all seam-based vertices and edges associated with the selected sub-objects. You can also use the Show Shared Subs setting to change the color of highlighted shared sub-objects. To see shared sub-objects in the editor window (highlighted in blue by default), turn on Display menu Show Shared Sub-Objects, or Unwrap Options dialog Show Shared Subs. Use the Stitch tools to connect selected sub-objects on a cluster seam to their shared sub-objects on another cluster's seam.
Both represent the same sub-object in the object mesh, but are represented twice or more in the UV mapping because of the subdivision into clusters. Most UV vertices and edges on cluster seams (that is, on the outer edge of a cluster) have shared sub-objects on other cluster seams.
