How to use Maya to build a credible human head model

First, Introduction

Building a credible human face is one of the ultimate goals of every three-dimensional artist. But to get real and natural works, we need to do our best at every step, including data collection, model planning, texture rendering and final rendering, and so on. In this article I explain the process of modeling and how to use Maya or other tools to complete the model step-by-step. such as: the flow of work, the different methods of modeling, the structure of the extension, common errors and so on.

Second, before the start of modeling preparation

Before I went into modeling, I studied how to get a good reference picture or to draw a concept map. These things have a very important role to play in our later modeling, and the quality of reference pictures and concept maps will directly affect the accuracy of my model. If we make a mistake in this process, it will be a lot of problems when we are modeling, maybe our model will match the positive picture, but the side does not look so. These mistakes will cost us a lot of time to revise.

If we're going to use real-person photos for reference, then the angle of the photo is very important, otherwise our model will be wrong and we'll have to spend a lot of time tweaking it. We also need to take into account the camera's focal length, the longer the focal length closer to the view of our reference model. In theory, however, because of the changes in the perspective of our photos are always different from the real people, we refer to the picture book model will be slightly fatter than the real person, of course, this problem can be resolved through later changes. In addition we also need to consider the picture of the light, too bright or too dark light pictures will hide a lot of details, so we can not use.

than the poor reference picture, try not to use the following picture

A better reference picture

Build a reference picture in Maya because of the difference in perspective, we can not directly from the camera to get directly to the Maya reference picture, we should be in Photoshop to further modify the image we need.

The following positive side details do not match
