Hi there, this is my first post on this forum.

I am trying to make a human face in 3dsmax.
I tried polygonal method before. but the result is not satisfactory.
So I tried again, from the basic reference line and image reference.

The overall progress is up to following:

I made the nose, then face and lips then jaw
but then when i need to connect the jaw and the face, I found that the number of points doesn't not enough. (See the following picture)

As far as I know, 3dsmax doesn't support pentagon as a polygon.
So how do I connect the jaw and the face?
I know we can cut the face and insert more points vertically, but this avoid me from keeping the face part clean (I suck on managing too many points, the face doesn't smooth enough)

So, I would like to know how should I deal with the problem? Is inserting point the only way?

Moreover, when I use polygonal modelling in 3dsmax, I run into some part ends with triangle, I guess there maybe no way to prevent this. However, are there any tips or better way to do it? When should we use triangle?

Thanks a lot.

triangles and 5 sided polygons are ok, as long as they are kept far from each other, and as long as they are as few as possible and not in areas wich deforms.

The best workflow is to model in concentric circles, thus you can add a lot of detail inside the decide dircle and usually you will end up with quads and with few pinches (areas where more than 4 edges intersect)

You may want to follow this link. is the best thing I ever came across.

You may also want to read some posts from the topology research in this category...I know some of the images are missing, but there are a few left, where can you watch other solutions...

Refer to those stickies to look over the wireframes for other peoples heads. There are tricks to solving problems with 3 sided, and 5 sided polygons, but I don't have the link handy. You might just want to try drawing some lines on a piece of paper and trying to figure out how to retain all quads. I have to mention, that all quads are not necessary but they have a huge plus.

In your case though, the easiest way to solve this problem is to start removing loops from the jawline so they match up with the rest of the face. If your going to be subdividing this head, theres no way your ever going to need all of those lines like that. They will simply work against you.
