Hi There!

I looked through some tuts and searched the forum on this but only came to some seam topics which is a whole other subject. Hopefully you guys can help

. I'm creating a new toddler top from a existing mesh (toddler dress with puffy sleeves) and thought that it might be a good idea to use the Mirror Modifier tool in blender to be sure of symmetrical sleeves.

I thought that if I box-select the area that i want to mirror it might work but unfortunately it also creates a mirror of the other parts of the mesh. That's what I think... because the circled areas flicker on the screen.

Is there a way to only mirror the selected part of the mesh? Or do I always have to chop the mesh in the middle and mirror it then? Good to know for the future!

I was actually almost done but then realized the flickering images might indicate a whole mirror instead of partial. Rookie mistake :Titter

I don't think there is a way to mirror part of the mesh with mirror modifier, I don't see an option to mirror by vertex groups. But you can mirror selection by duplicating it (Shift+D or Mesh -> Add duplicate). After this you will need to mirror duplicated part by x axis by pressing Ctrl+M and X. Before mirroring duplicated part you need to make sure that pivot point set to the center of the mesh, and not somewhere on the sleeve. For this you need to press Ctrl+C (this will set cursor to the center of the mesh). After setting cursor you need to set pivot point to cursor (see the picture).

When I mirrored selection, I noticed that normals got flipped. I have no idea why it happens to be honestly. If it happened to your mesh, you need to recalculate normals.

Hi Feyona!

Thank you for your pointers! :Tup

I removed half of the mesh and set the pivot point to center and then applied the mirror modifier. It's worked! Only got a message in the command line of the blender screen that said; Applied modifier was not first, result may not be as expected
which I didn't fully understood :confused

Since the mesh looks fine and also in S4S nothing seems off. But anyway it works :D! Thank you!!!

EDIT: I think the command line message appears because the geom skin modifier was first, not sure though.

Renorasims what you did is a workaround

, but totally applicable. If you use mirror modifier, I believe you don't need to set any pointers to the middle of the mesh, unless you were moving around that mesh in object mode. When you apply mirror modifier, it mirrors according to where origin set (orange dot that you can see in the middle of the grid on the bottom of the mesh). The only case when it moves from the center is if you move the mesh in object mode, otherwise by default it's always in the middle.
