hey guys, i got a problem.
i imported a mesh from 3D Max to Zbrush.
but when i sub-divided my mesh in Zbrush it just breaks!
way dos it do that?
her is a image to illustrate what i mean.
the top image of my gun is divided and the bottom is just a imported mesh from 3D max, this model is not sub-divided.
thanks for your help

It’s mainly a lack of edge loops in those areas from Max. In ZBrush, you can turn Smt off for first couple of subdivision levels then turn it back on for more subdivisions. The problem with that though is the round portions won’t subdivide like you would want them to. Do a Groups Split to divide your Max sections into different subtools then do the smoothing on the individual components with Smt on or off where needed. You can learn a lot by experimenting.
Alternatively, weld the vertices when you export.
When you subdivide a model the smoothing algorithm causes the surface to contract. When this happens at the edge of an object, the edge pulls in – especially at the corners. That’s exactly what you’re seeing in your screenshots. Those areas where you’re having the problem are places where points from two separate surfaces overlap. So when you divide the mesh, they pull apart.
There are actually three methods you can use to prevent this, depending on the needs of your model:
Welding will merge overlapping points.
Edge loops will add extra geometry that hides the contraction around the edges. (It still happens, but you don’t notice it because edge polygons are really thin to begin with.)
Tool>Geometry>Crease will also prevent the edges from contracting. Apply that before you divide.
Hey. thank for your help. i really appreciate all of your help.
its nice to see, som one who helps an another in there problems.
thank alot your all awsom.
peace
