Open wing01.gmax or continue with the current file. The completed file for this section is wing02.gmax.

Now that the Multi-Material's name has been changed to Wing_Material and the sub-material's colors have been changed. The Material IDs can be reassigned to aid in UVW mapping. Close the Material Editor and Material Navigator, if they are still open. Select the wing if it's been deselected. Go to the Modifier stack and select "Polygon" sub-object level. Move back to the top viewport in preparation for assigning IDs to the wing. At this point, the wing only has one ID and it's ID 22. Next step is to break up the wing with multiple IDs 1 though 22. This will be accomplished by carefully selecting individual polygons or groups of polygons and changing their Material ID at the sub-object level. Before starting this process, you will need a pencil and paper. Write down the IDs and a short description of them as they are assigned to different parts of the wing. All of this work may seem a bit daunting and tedious at first, but the payoff will be well worth the effort. It also helps to plan ahead as to how the IDs will be assigned to the wing.

Start in the top viewport short cut "T" and expand the viewport short cut "W". The wing should be entirely selected at this point. Left click in the viewport to deselect the wing. Turn on "Ignore Backfacing". With the wing deselected, choose the polygons that make up the top portion of the Ailerons and Flaps. In the "Surface Properties" rollout, change the Material ID entry box from 22 to 1. From this point on, be sure to separately write down a short description for the material IDs. Write down: "ID 1 = Ailerons and Flaps top side. Be sure and use the Active Shading "F2". It is built-in to help with this type of work.

Material ID #1
Description: Ailerons & Flaps Top side

Notice how the Ailerons and Flaps changed their color to green. This is due to the color of the Multi-Material's first sub-material.

Use the following images for your ID pattern.

Material ID #9

Material ID #10

The polygons on the bottom of the wing are mapped using the same procedure just performed. Select the bottom short cut "B". When the bottom half is started, pay close attention to the gear bay door areas. Also, look closely at the wing tip trailing edges. There could possibly be missed polygons in these two locations. Zoom in and look closely for black areas missed. If there are any at all, determine which Material ID they belong to. Select them and change the ID. A missed polygon will cause strange results later in your work.

Save the file as My_wing02.gmax

Section Three will mainly cover the bottom of the wing with close attention given to the gear bay doors.
