Hi
Just started using zbrush today…
If I ctr z more than a couple of times my model disappears when I choose that brush again it wont let me edit. Ive discovered that I have to go to display and click double sided and then click about like a mad person and then it sometimes lets me edit again.
Can I extend the undo facility like in maya and what is this edit thing about.
please help a poor nooby
Your problem is a bit confusing to sort out. Perhaps you can’t sculpt because you’ve gone so far back with undo’s that you are looking at a 2.5D image of the mesh and not an actual polymesh.
I’m guessing you hit “undo” to the point before you selected MAKE POLYMESH. If you can’t edit the mesh first look at the edit button to see if its active. If not turn it on. And also check the UV subpalette to see if you have UV’s. If not hit Make Polymesh and try sculpting.
Thanks Nancyan
I didnt think i had undone that far back but maybe I had.
I had imported a head model from maya and it seems double sided must be checked, the problem then was that the edit button refused to become active even after checking Make Polymesh - if it happens again ill look at the UV thing as you say, I guess it should be turned off?
Since then Ive encountered another problem - when i press X on the key board for symmetry I get it at a diagonal…cant find how to control this
Sorry best go through my teething problems alone - no pain no gain :eek:
Is the symmetry diagonal relative to the model, or relative to the canvas?
If it’s relative to the canvas that’s normal. Symmetry always operates based upon the model’s local coordinate system and since the model can be rotated any which way on the canvas as you work, the symmetry will move along with it.
If the symmetry is diagonal relative to the model then the model isn’t centered very well. You’ll see this if you look at it in the Tool>Preview menu. That window shows the model’s local coordinates. Y is up/down. X is right/left. Z is toward/away from the camera. If the model isn’t squared within that view, symmetry will work oddly. You should use Rotate deformations to fix it or try using Poseable Symmetry instead.
Yeah got it! - thanks aurick - it was relative to the model, rotated on z and hit shift…
great stuff!
