6. Unwrapping the Pipe Controller Box

Step 1

With the pipe controller box polymesh selected, go to Show > Isolate Selected and check on View Selected command to isolate the selected object.

Step 2

With the entire surface faces selected, go to Create UVs > Automatic Mapping command.

Step 3

You can see the unwrapped UVs inside the UV Texture Editor.

Step 4

Invert the face selection mode to select the cover poly mesh. Go to Create UVs > Planar Mapping.

Step 5

In this way, you have unwrapped the pipe controller box polygon mesh. Now, you have to attach the distracted UVs according to the polygon shape by using Sew UV Edges command.

Step 6

For using Sew UV Edges command, you have to select the edges inside the UV Texture Editor. So, being in the edge selection mode, select an edge. After selecting an edge, its mutual corresponding edge which you would attach it with, would be highlighted automatically.

Step 7

With the corresponding edges selected, go to Polygon > Move and Sew UV Edges command inside the UV Texture Editor window.

Both UVs are attached now.

Step 8

In this way, you have to attach multiple UVs to form a complete unwrapped and boxed shape as shown in the following image.

Step 9

In the same way, you have to attach the gapped UVs. So, with the corresponding edges selected, go to Polygon > UV Texture Editor > Move and Sew UV Edges.

Step 10

After completing the unwrapping of the pipe controller box, arrange the UVs layout as shown in the following image.

7. Unwrapping the Dial Case

Step 1

With the dial case mesh selected, go to Show > Isolate Select and turn on View Selected check box to isolate the selected object.

Step 2

With the dial case mesh selected, go to Create UVs > Automatic Mapping command.

Step 3

You can see the result inside the UV Texture Editor window.

Step 4

With the inner border edges selected, go to Polygon > Move and Sew UV Edges command.

Step 5

This is what you would get after sewing the extracted UVs.

Step 6

In this way, you have completed the back side projection UVs as shown in the following image.

Step 7

Following the same way, complete the other side’s UVs also.

Step 8

With the back side’s faces selected, go to Create UVs > Planar Mapping command.

Step 9

Following the unwrapping method stated in the earlier steps, unwrap and sew the UVs of the back faces.

Step 10

Scale down the UVs and fit them inside the layout area.

8. Unwrapping the Under Section Pipe Channel

Step 1

With all section pipes selected, go to Mesh > Combine command to attach all selected pipes together.

Step 2

Isolate the pipes. With the faces of the pipes selected, go to Create UVs > Planar Mapping command.
