The edges of the texture image extend beyond the edges of the model image. Because this is going to be used as a projection, it is better to give some leeway beyond the model. Any image that extends beyond the model in the 3D paint package will simply fall outside the boundaries of the model and will not be used. Also, Deep Paint will allow the parts of the image that should not be used in the projection to be erased before the image is projected on the model. It is simpler to create data that will be thrown away later than to add that additional detail later on.

The Side View
The side view (Figure 27) shows different challenges than the face and top views. In this section, the legs of the bird need to be addressed, as well as the side of the body.

The hawk’s feet are color corrected to the right color and then cloned to create the shape of the model. This is all that needs to be done from this side. Normally, the side of the face would be done at this time also. However, lots of blending will be done on the face using the image created for the front projection of the face; no additional work will be needed in the side view.

Creating these images using this technique may seem like a lot of trouble to go through if there is a 3D paint program available. However, if these images are accurately and cleanly created in 2D using Photoshop before projecting them as 3D textures, this process should save time in the long run. The blending and painting done in most 3D paint programs do not give the textures the kind of color and detail consistency that can be achieved using this technique.

The model will be imported into Deep Paint for 3D texture projection. There are options available for importing the model into Deep Paint from Maya. Deep Paint has a great plug-in that can be used to import the model and textures from Maya into Deep Paint. This plug-in creates a special texture node that loads multiple image-based texture files into a single texture node. The process of loading many image-based texture images with very cryptic names into Maya for rendering is made easy and seamless. But, if there is a need to access the individual texture images, these complex texture nodes created by Deep Paint are difficult to extract specific data from. This process can either save a lot of time or cause confusion depending on the final requirement. For the purposes of this tutorial, the Maya plug-in for Deep Paint will not be used.
