3d Character Modeling Tutorial

3D models serve many purposes.


3D models have become a part of almost every type of media, from television and movies to video games and even printed ads. These models are created using 3D modeling applications like Maya, Cinema 4D or Hexagon. Although the particular tools used in these programs may vary, there are certain basic principles you should use in any of them when creating a 3D model that you intend to rig for posing and animation.


Instructions


1. Create models that do not have perfect bilateral symmetry. Of course, if the character is a human being, he has to have two legs and two eyes. And the general features from left to right need to be similar enough so that it seems to be from the same person. But an exact mirror image will seem unrealistic.


2. Ensure that all of the polygons that need to be "outfacing," are indeed, outfacing. If you have a flipped polygon, it will render as a hole in the model. While working in the modeling program, you should be able to tell if a polygon is flipped because the color is slightly different.


3. Create enough polygons in all the bendable areas of the model to ensure that joints and other parts bend realistically. A low number of polygons in an area like the elbow for instance can lead to crimping when the joint is bent. On the other hand, eliminate any unnecessary polygons in areas that don't need them, since this will make the file size larger than it needs to be, slowing the rendering process.


4. Export your model (if you want to use it in another program like Poser or Daz Studio) in Wavefront OBJ format. This is the most commonly used format, and can be imported and used by virtually all of them.
