Problem: one face too much

[Madeliefste Oh]

I made a model that looks different when I upload, then it looks in my 3d prog (C4D). There is one face too much on the model in SL.

 

The strange thing is that the frontside shows normal in SL, but both front side and back side were contructed the same way.

Can anybody tell me what is happening here. Why do I get one extra face in SL?

And how can I get rid of it?

[Madeliefste Oh]

I was able to solve it by making an extra cut (yellow line).

But I'm still curious, why the model doesn't upload good without this cut, while the front side shows right without this extra cut. So if anybody has an explication for it...

You have to stay away from faces with 5 verts.  That's what causes it.  With the cut, you have a triangle, with 3, and a rectangle with 4, (which can be split into 2 triangles if you added one more cut, which wouldn't affect anything.)  You can generally remedy it just as you did by adding the cut, so, you came to the right conclusion, just not sure how.  Hope that clears it up.

Did you have an Ngon in your model when it was inside your modeling program? 

[Madeliefste Oh]

Yep, I had an Ngon with six points.
