You probably noticed that when you loaded the topProjection map as projection, a green line appeared in the top view (Fig. 6). If you change to Perspective view, you will see that what appeared is not a line but the projection plane (Fig. 7).





Fig. 6 - Fig. 7

Since we need to project the texture map onto the top of the model we have to rotate the projection plane:

1. Go back to the top view
2. Window>Rendering Editors>Multilister�
3. 2Click(double click) on the projection icon (Fig. 8)
4. Click the place3dTextute tab in the projection window that opens
5. Write -90 in the Rotate field under Transform Attributes (Fig. 9)
6. Click the Fit to group bbox button under 3D Texture Placement Attributes (Fig. 10)

Fig. 14

As you can see (Fig. 10), clicking the Fit to group bbox button the projection plane changes its position and scale because it fits the model (Fig. 11). But from a closer view you can see that the projection plane is few pixels away from the border of the model (Fig. 12). This because the projection plane considers the CVs and not the geometry, as you can see in (Fig. 13) and (Fig. 14) (remember that the CVs of a NURBS surface can lie away from the geometry).



So, if you render the top view you will see something like the picture below (Fig. 15):



Fig. 15

This happens because you have to scale and move the projection plane untill it fits the geometry.

1. In the top view select the projection plane
2. Move the Scale/Move handles (Fig. 16) untill the projection plane fits the tortoise shell (Tip �the handles don�t appear, click   the on the shelf)





Fig. 16 - Fig. 17 If you need to rotate the projection plane click the cross

Go very close to the projection plane to be sure it fits the model (Fig. 18)



Fig. 18

Adjust the projection plane untill in your rendered image correctly appears the border all around the tortoise-shell:





Fig. 19 - Fig. 20

As you can see, now, the border runs all around the model (Fig. 19).

Another important particular to notice: the "excess" of gaudy color (Fig. 20) doesn�t appear on the top of the tortoise shell and, at the same time, allows little imprecisions:
