Vertex Rollout

In this rollout everything dealing with vertices is handled:

• Target: Target weld. Similar to Edit Mesh, including the screen pixel range for snap. There are two additional checkboxes for target weld:
• UV: Switches the UV correction for target weld on or off.
• Col: Switches the color correction for target weld on or off.
  
  The vertex target weld contains an uv correction feature, which corrects the uv coordinates directly while you weld.

  Additionally, it has a color correction feature, which corrects vertex colors while you weld:
  
  

  before Target Weld	Target weld (uncorrected)	(with color correction)

  
  
  
  

  Unfortunately, UV correction is to "handle with care": · be sure to weld only neighboured vertices. If any other vertices are welded, it behaves like the original target weld and the uv coordinates are not corrected. · it won't work with differing uv coordinates. This is not a bug, it is technically impossible to correct uv coordinates in all cases. So it only works with polygons containing constantly repeating texture tiles. A workaround for this is to set edge visibility consequently for parts using different tiling (or, of course, split the mesh into pieces and handle each separately). The edge visibility is taken into account; so you should consider using edge visibility if you are working on meshes with different UV tiling. Note that mirrored coordinates means different tiling too! Of course, if you are working on meshes with constant tiling, you needn't look for the edge visibility.        Examples: a) CORRECT:
  before Target Weld:	after Target Weld:
  The tiling is constant, so edge visibility is unimportant and the UV correction is done properly. b) CORRECT:
  before Target Weld:	after Target Weld:
  The tiling is different, but the edge visibility is correct. The faces with different tiling are separated and the UV correction is done properly. c) INCORRECT:
  before Target Weld:	after Target Weld:
  The edge visibility is wrong. Faces with different tiling share the same polygon. Mesh AK can't decide which is the correct UV correction and so distortions occur. d) INCORRECT:
  before Target Weld:	after Target Weld:
  The edge visibility is wrong too. The faces sharing the same UV tiling are not in the same polygon, and so Mesh AK again can't decide which is the correct tiling, and distortions occur again.

  
  
  
• WeldSel: Weld selected. Similar to Edit Mesh, including the weld range spinner
• Average: Averages the selected vertices. Pretty similar to weld selected, but the vertices only change the position and are not really welded. The benefit of this is a) that it doesn't change the topology (useful for Poser/DAZ meshes, where you mustn't change the topology) and b) it works across multiple objects. E.g, if you have two planes, you of course can't weld the border vertices of these together. But you can at least average them together to match them at exactly the same place.
• Collapse: Collapse. Similar to Edit Mesh
• Create: Create. Similar to Edit Mesh.
• RmIso: Remove isolated Verts. Similar to Edit Mesh.
• Reset: Resets the selected vertex positions (Throws away all movements in this modifier). Soft selection is supported.
• Grab: Resets selected vertex positions partially, or grabs vertex positions from the modifier stack. In the Grab Vertex Position Dialog you can adjust the amount of the changes. Soft selection is supported.
• Fit: Fits the selected vertices onto the surface of another object . First, you can pick another object, and then the Fit Vertex Positions Dialog is shown to adjust the amount of the changes. Soft selection is supported.
• View: Align to view. Similar to Edit Mesh.
• Grid: Align to grid. Similar to Edit Mesh.
• Plan: Make planar. Similar to Edit Mesh.
• X/Y/Z: Make planar in x/y/z direction.
  
• VertCol: Set vertex color. Similar to Edit Mesh.
• Ch: Vertex color channel. Channel 0 is the default vertex channel usually used for vertex color. But for special purposes, you can use all other mapping channels too. The VCol checkbox of the selection panel, which switches vertex color on and off, always refers to this channel.
• AdjCol: Adjust vertex colors. Puts up the Adjust Vertex Colors Dialog, where you can "fine-tune" the vertex colors of the selected vertices.
• Filter R/G/B: This can filter the used vertex color to selected color channels, while other colors floating up the stack are left untouched. This is extremely useful if you have to work on color channels separately, e.g. if you are working on a realtime export scene, where landscape materials are determined by vertex color channels (green=grass, red=earth, blue=water).
  
  An example:
  

  The lowest Mesh AK modifier has "B" switched to on and all other to off, so it stores only blue color.

  The Mesh Army Knife in the middle of the modifier stack has only "G" switched to on and so only stores green.

  The Mesh Army knife on top only stores the red channel.

  All modifiers together give a mix of red, green and blue.
