Still some pinching issues on my model

[rouge]

hi everyone,

i got rid of some pinching on my head model especially around the eyes and nose but now i have created some new ones on the nose i followed the method of adding edges and merging polys but i always end up with ngons and more tris i don't think i am going at it the right way and i feel lost as to how to proceed with add edges and merge polys i've also used fix 3-5 which has help but i'm still stuck with the pinching heeelp please.

If you know the polyflow you are looking for, that method will work. I am a bit busy now, but if you look back over the the thread I gave you, you can study the polyflow of a head. I would suggest taking one of those examples and try to duplicate it on your model. For instance you still need a full loop around the eye.

You really don't need to consider proper edgelooping or polyflow to get rid of the pinches though. All you need to know is that subdivision algorithms prefer four polygons (or edges) per point. Pinched areas generally have more than or less than four edges/polygons connected to a point. And this causes lower or higher "stress" in those areas which manifests as pinching. When you have two or more of such points right next to eachother the pinching is magnified.

Try to always get 4 polys/edges per point. Commonly this is impossible to maintain for anything but the simplest of meshes. In those cases prefer points with 5 edges connected to anything else. Do 3 if you really want to keep the resolution down. Never do 6 or more, because you shouldn't have to.

Those are all good points. Things you need to be aware of. I go into that and much of my theory behind it in my tutorial on sub patches.

thank you for the replies and patience.

as i said before i'm new to modeling and i learned a lot from you guys. I understand the concept of polyflow but find it a bit difficult to actually doing it i guess with time and practice and better planning i'll get the hang of it.

Yes. It does take doing and over time. But you can also learn a lot just by simply duplicating what someone has done.

Try taking a pencil and a paper and look at some head examples and sketch out the polyflow. You don' have to be a great artist. Just sketch out the lines and see how they all go together. This is just another way to get a tangible feel for it without going through the laborious steps of modeling it.

Then on the modeling side. Try going back a step. Rather than try a whole head, just work on the polyflow of the eye area, then the mouth and nose. But do each separately and don't worry how to connect them just yet. Use the examples given by Jeffry as a reference. I think you'll start to get the hang of it.

By the way, I have done all these things myself along with also doing many many head models and I am still trying to get the hang of it. :)

It's free, the exported human is 11,490 faces with edgeloops.
This should solve the pinching problem.
