Hi i can do this with single command in Modo, but hard to find the sama function in Blender. Can anyone help ? pls see the attachment , i have 8 vertices and i want to merge so the adjacent vertex will blend together , to say to become 4 vertices. The mege vertex in blender will merge them all together become 1 single vertex. Or i have to do it for every 2 vertices and repeat the same process. Look, this is just the simple example. We may easily fix this using other method like dissolving edges etc. So here's the real case : I have a head model which is very high detail polygon. There's imperfections of previous edit , so there's some vertices which is look like single vertex but if i zoom it really close , i found 2vertices (also can be 3 or more) that are really close to each other . The problem is it happen sporadically randomly spread acrross the model. I can't inspect one by one as it's hundreds of poly.

So in modo i have a very handy tool that can fix this in single click. WHere it scan the overall model and find each the adjacent 2 or more vertices (at the treshold we can set ) and blend them. And repeat the process automatically until all vertices is fixed.

In Blender , i can't find that tool. So i have to find it myself and merge them. Can someone tell me where is this tool ?enter image description here

    $\begingroup$ It's called remove doubles and accessible through the Specials Menu: w > remove doubles. You can adjust the merge distance after applying the operation in the tools panel. $\endgroup$

  • $\begingroup$ @ceg I would have expected this to be a duplicate, every 10th question includes a remove doubles or recalculate normals. $\endgroup$

  1. Select the geometry in question (or all geometry with A).
  2. Remove double through the W specials menu.
  3. Adjust the merge distance if needed.

enter image description here

From the manual:

Remove Doubles is a useful tool to simplify a mesh by merging the selected vertices that are closer than a specified distance to each other. An alternative way to simplify a mesh is to use the Decimate Modifier.

Using the decimate modifier will be not pay exceptional attention to the distance though and is in this case not useful.

With Blender 2.8 (non-beta) out, now there's a Merge Vertex by Distance tool within the merge tool itself. The quick way of using it is to group-select all the vertices that needs to be verified, press ALT + M and select "By Distance". Then entering the right distance will merge all exceeding vertex within those selected.

    $\begingroup$ That's not a 'tool'. That can be called an operation or a function or an operator, but it's best not to call this a tool, because tools are different things in Blender now and this might confuse people new to Blender. $\endgroup$ Nov 5, 2019 at 22:03
