Exporting Mesh problem
Ive got this character that I have been busy modeling in Maya and I got to a point were I want to export parts of the mesh into Zbrush for detailing.
Before exporting it to an OBJ file I give my mesh a quick check for any faces with more than 4 vertex points, however when I attempt to import it into Zbrush I get a warning message (See attached files) telling me that I don't have the correct subdiv level. I got around this by going back to maya and reversing the the face normals.
BUT! the big problem is when I finally get it into Zbrush and subdivide the mesh it explodes (see pic's).
Can anyone please help me.

Don't be satisfied with what you can do but rather strive to do the things you can't do!
Exceed Expectations!

Sorry about the massive pictures.
I have spent all day trying to sort the problem out and I think I might of found a way around it. I will do some more investigating before I say anything, so that I know what was wrong and know I'm talking about.

Whenever you edit the model, cut faces, delete edges, etc, the vertex id is reassigned. This means that what was once vertex 27, could now be vertex 214.
When you try to import this back into zBrush, it looks at the old model, and tries to map the high definition detail back onto those specific id's. So if a vertex was on a hand in the original model, but on the new model, it's on the knee, you can see that there will be problems.
Once you import your obj into zBrush for the first time, DO NOT EDIT IT IN MAYA! You will break it!
With your problem, you should be able to fix it by creating a new canvas, and importing the base model from Maya. What it's trying to do right now, is it's mismatching the number of vertex id's. Say a model with 200 vertices, to a model with 178.
Hope this makes sense.
Imagination is more important than knowledge.
