mirroring problem : Solved!

[stoertebeker]

First of all all: hi to all the fellow blender geeks out there!

I'm currently modelling a human head and am nearly finished with the modelling itself. I did the head and left out the ears for obvious reasons (hard to model so better do it when you feel like conquering the world).

I modelled the head with the mirror modifier. Today I felt its about time to shape the ears and add them to the head and there is my problem:
When I merged the two objects (did the ears on another layer) the mirror modifier went poof. No problem I thought. Just add the modifier again.
For some freaky reason the mirroring doesn't work like it did before. The mirrored object is rotated a bit and I have no idea why and how to change it.





The screenshots are showing what is happening. I want to mirror the head along the z axis but for some strange reason the mirrored part is a bit rotated.

Any hints?

Thanks in advance.

cheers,

i had the same problem once.

if i remember well:

I rotated it in edit mode until it is good than left the edit mode and rotat it to put in nice and strait.

hop that helps



ow and welcome to elysiun.
and start on your model too

Thanks for the hint. I followed your advice and got it somehow right. But it doesn't look as seamless as it did before. Also it is really nasty to readjust the mesh. A lot of try and error without the perfect output:



I wonder if rotating the ear-object before joining the head caused the mess.
There must be a reset-alignment function somewhere .. or am I dreaming?


Thx a lot for the help though ... I guess I can continue modelling now (hope so at least).

Alright .. I figured it out.
Make sure you place the mirror modifier above the subsurf modifier (move it up by pressing the triangle).
If the seam still looks kind of messed try setting the 'Merge Limit' up a little. Just as much until the seam is smooth.






thx again!

Got an interesting answer on another board:

"i did a little testing and it seems that it's caused by the order in which you selected the two meshes before joining. the last mesh selected becomes the new merged mesh, so it's local cordinate system is the new local coordinate system.. in other words it mirrors with respect of the z axis of the ear. to solve this you should first select the ear then the head before merging... hope you understand what i mean"


So keep in mind in what order you click your objects!
