working on model only using edit mode,i work my way up sub divisions adding detail and hide parts of body and work on a small section at a time.
i finished at lunchtime and save file.I have been working this afternoon and unhide all before i saved and noticed this big triangle even when i drop to level 1 there is still a problem(looks like a point has been dragged all across screen)
How did this happen?
And how can i correct this please?
I have also posted on zbrush central and this is the 1st time i havew been able to get to my pc in a while as my apartment has been redecorated.
Earlier feedback suggests that i drop to lowest sub div level and take back to max8 and fix vert or delete bad side mirror ands bring back to zbrush-if this is the way what about the higher sub div levels(upto 6 in total,unlikely i could export highest sub div to max,nearly 2million polys).
Also the model was unwrapped/uvw mapped before i took her into zbrush, is this going to cause trouble if i mirror.
Please,i am on bended knee for your help and advice.I have spent a lot of time on her and really dont want to start over, cant for the life of me figure how this occured as i only work in edit mode and on small parts at any one time.I always back up my work to disc but only ever overwrite previous file. my only other saved file is on an external hd but that was 5 days before this and would still require a lot of work just to get to wherer she is now.
thank you.

i decided to export sub div level 1 model back to max.

the triangle present turned out to be a vertex from her little finger that somehow had attached itself to the front of her hat.

I fixed this and imported back to zbrush and old level1 with fixed one,

however when i went up through the sub div i got weird results as sceenshots show.

I am guessing that the problem here could be with the obj.Exporter settings in max 8

the settings that i checked are-

Group and material-group by Object

Geometry-rotate model

Faces-Quads

Texture cordinates

normals

smooth groups

vertex scale 1

file-# of digits 6



Everything else remained unchecked.



Hope you guys can help

I am not a 3DSmax user but I believe it is important to have both the right .obj import and export settings.

Use the settings from >> This << (http://206.145.80.239/zbc/showthread.php?t=17027) thread and try again. If that does not work either try performing a Reset XForm in 3DSmax or collapse the stack to an editable polygon object and export again. In either case your vertice order is being changed at some point when in 3DSmax, which results in messed up geometry back in ZBrush.
