Subdivison problem


(r0x0r b0x) #1

Ok, I’ve been working on my first Blender model for awhile now, but now I’m stuck with this one part. I made hands for the model, but after finishing other parts and looking back I decided that I didn’t like them since they were so misshapen and the mesh itself is all distorted from my inexperience.

So I decided to delete the hand I had and start over. I just selected the faces and deleted them.

So then I figured that I could just select all the vertices around the hole and then use fill (shift+f) to fill it in. Then I could just extract the new face and rebuild the hand. But something strange happened when I tried to fill it in:

You can already see the problem with the subdivision. It seems that the new filled part is being subdivided differently than the rest of the model. A little bit further down the arm you can also see a little artifacting thats goin on. The problem becomes more apparant if I extrude those stump faces:

Obviously something is up. I’m not sure what it is though. It seems that the rest of the model is smoothed out more even if they’re on the same subdivision level. Strangeness. Hopefully this is a really common n00b problem and someone can help me easily. Thanks.

The subdivison is working fine… what’s wrong is that the new faces are not ‘Smooth’ by default. You can select all the new faces and click the ‘Set Smooth’ button, or just go to Object Mode and click ‘Set Smooth’ for the whole object. That will get rid of your lines.

Have fun!

Heh… that was a pretty noobish question. Thanks for the ultra speedy response.

But something strange happened when I tried to fill it in:

It filled it with Tri’s and the original is built with quads. Select all tri faces in edit mode and hit J to try join them to form quads.

It seems that the new filled part is being subdivided differently than the rest of the model.

The new geometry isn’t yet set smooth. In F9, Link and Material tab hit “SetSmooth”.

When you show meshes here it’s better to do it without the “Optimal” button on. That way we can see the real geometry.
