more than 4 sided faces problem form Zbrush

rombick

When i exported my model from Zbrush , it tells me that there are faces with more than 4 sides , when i run clean up. But when selecting those faces and counting edges and vertices it comes up all correct quads. Am i missing something? i have a lot of those on my model and trying to figure out the way to fix it

Cleanup doesn't lie, so there's something wrong with whatever it has selected. Perhaps there are stacked vertices. Selecting the verts in the affected area and doing Edit Mesh > Merge (assuming Maya here) should resolve such a problem. Run another cleanup afterward to make sure.

merging vertices doesn't help, only way to fix it that i found it to delete the face and fill hole or append polygon in there. but that is very tedious process. And i would like to know the root of the problem it self? and i checked it has the right amount of edges and vertices, i'm very confused that never happened before.

It's hard to say what a cause would be because it's completely based on how you modeled your object. Some screen shots or access to the model itself could help with a more specific answer.

There are more options further down in the Cleanup menu, the only thing I can think of is that you have other options checked like faces with zero map area or something.

ok, you were right about the zero map area, thank you.

But now i have another issues, approximation Subdivision node doesn't work , mental ray fails render when it is applied to the mesh. i thought that the problem was that it was mesh.
