Problems with symmetrical sculpting

[Anonymous]

I'm having a few issues with sculpting a waist/midsection symmetrically. My first issue is when I duplicate special I cant get anything to persevere the seam of the mess. Not even the "persevere seam" check box works, its under the move or selection tool settings so maybe its the wrong check box. In the first case moving verts and using sculpting brushes are all still breaking the seam of the mess. The second is when I just mirror the mess, make it the whole part and turn on the X-axis summitry of the sculpting tools and the and the center point it is finding is off to the left for a reason. From what I can tell the mess is perfectly symmetrical on the X-axis so I don't know why Maya is not finding the center of the mess. I would love to find the solution to both issues but I am fine with just getting one to work the way I need it to. I can post pics I just haven't got them yet. Anyone know what to do or try next?

I believe you mean mesh… Try to  delete half of the model and then mirror it with "merge the border verticles" so you are sure that it is symetrical. Also if it does not work check the option world symetry if you have your model exactly in the middle of a grid. Try other axis, to be sure that your symetry isnt in the different axis. Or post your model.

I didn't get any of that to work but selecting "world X" in symmetry setting did get the seam persevered when moving vert's and edges with/without soft selection but sculpting brushes still broke the seam of the model when duplicated special. Here is the model to is if you or anyone can find out what I am doing wrong.

Its absolutely  okay. But you have that as two separate objects. You have to use combine, then select the verticles in the middle and merge them to have one body. Or, mirror (use mirror, not duplicate special) the one half and turn on "merge border verticles" and it should automaticaly be a one object. When you have to separated halfs it will act like that and the seam will broke.

I did get sculpting brush mirroring to work with "world X" and not "object X" (I thought I tried it before but I ether messed up or missed it) and I can get that to work but with a little extra effort on my part but here is the issue I have with that that. World X mirroring is mirroring and not symmetry, when the brush crosses the line of symmetry it doubles up on itself until it fully crosses over to the other side and then it becomes symmetry again (At least this is how it looks like its acting when I use a brush with exaggerated settings, like a lift brush). That center line is a place I want to focus on for this model and mirroring makes that harder in that tight space. The ideal thing to find is a way that I can use Duplicate Special and have sculpting brushes not break the seam of the mesh. Because then when the brush crosses the center line its influence will be terminated and then Maya will create symmetry with the duplicated special. From what I know you can easily take a duplicated special and make it a one piece mesh when your done. 

So from what I know and my current level that is what I think would be best but this is turning out to be kinda a tricky issue to get things to work the way I want it to work. Right now I found that the thing I have to do it when I am working on anything but the center line I keep World X on and I am good but when I am working on the seam I have to turn it off and then be extra careful or even pick what I think is the better side and mirror the object again. But the human form is not exactly symmetrical and the brushes settings are really low so IDK how much that even matters at the end of the day.
