Tutorial 2: More Basic Modelling and Texture Mapping part 3

 

We still have problems. First the texture is backwards - you can tell by looking at the text in the texture map. Let's fix this - In the Modify panel, look under Parameters, then look for U Tile: Click in the check box for Flip. Ahhh, that looks better....

 

We still have a problem. We've got the top and side texture showing up on the side and it's the wrong size. We're going to fix this by editing the texture coordinates. Go to the Modifer List box again - click on the down arrow and under UV Coordinate Modifiers, select Unwrap UVW.

In the Modify panel, under Parameters, click on the Edit button. The Edit UVWs window should open. Click and drag a selection box around all of the texture vertices in the Edit UVWs window. They should all turn red to indicate that they've been selected.

We're going to scale the texture vertices. In the Edit UVWs window, click and drag down on the Scale Icon. Move the mouse pointer to highlight the lowest icon, then release the mouse.

scale the texture vertices. In the Edit UVWs wi
lowest icon, then release the mouse.
This will only scale up and down. Move the mouse pointer over any red selected vertex until the mouse pointer chages to the scale icon. Click and drag down now - the vertices should scale. Scale it so it is half its size. In the Edit UVWs window, click and drag down on the Move Icon. Move the mouse pointer to highlight the lowest icon, then release the mouse. This will constrain us to only up and down movement.

 

Move the mouse pointer over any red selected vertex until the mouse pointer changes to the Move icon. Click and drag down now - the vertices should move. Move the vertices until it looks like the picture to the right.

 

You've just done your first texture map editing!

Go ahead and close the Edit UVWs window. We still need to map the top of our object. In the Modify panel, go to the Modifier List and click on the down arrow. Under Mesh Editing, click on Edit Mesh. .

 

Click on the Polygon icon. Under the Polygon icon, click on Ignore Backface, then in the Perspective view, click on one of the top polygons in our object.

Hey! I can't tell if I selected it! Let's turn on show edges so we can see what we are picking. Right click on the word Perspective in the Perspective view. In the pop-up box, select Edged Faces.

We still need to pick the other faces, so hold down the CTRL key on the keyboard and click on each of the remaining two top faces.

 

In the Modify panel, go to the Modifier List and click on the down arrow. Under UV Coordinate Modifiers, select UVW Map. Notice this time, the orange mapping gizmo is not oriented for the top polygons. In the Modify panel, under Alignment, click on Y, then click on the button below it labelled Fit. Also, look under Parameters and click on Flip next to U Tile: like in the previous steps.

Our top texture map coordinates are now ready for editing. Go to the Modifer List box again - click on the down arrow and under UV Coordinate Modifiers, select Unwrap UVW. In the Modify panel, under Parameters, click on the Edit button. The Edit UVWs window should open.

Click and drag a selection box around all of the texture vertices in the Edit UVWs window. They should all turn red to indicate that they've been selected.

We're going to scale the texture vertices. In the Edit UVWs window, click and drag down on the Scale Icon. Move the mouse pointer to highlight the lowest icon, then release the mouse. Just like before.

This will only scale up and down. Move the mouse pointer over any red selected vertex until the mouse pointer changes to the scale icon. Click and drag down now - the vertices should scale. Scale it so it is half its size. In the Edit UVWs window, click and drag down on the Move Icon. Move the mouse pointer to highlight the lowest icon, then release the mouse. This will constrain us to only up and down movement.

Move the mouse pointer over any red selected vertex until the mouse pointer chages to the Move icon. Click and drag down now - the vertices should move. Move the vertices and scale it (up and down and side to side)until it looks like the picture below. - try using the other constaint icons for both move and scale.

 

Go ahead and close the Edit UVWs window. We need to Bake down all of our Editing. To do this, Right click in the lister box under the Modifier List box in the Modify Panel. Select Collapse All in the pop-up.

A warning box will pop-up - click on Yes.

Now, before we check out our new modifications. We need to attach the object to the Dash9. Click on the main body of the Dash9. In the Modify panel, under Edit Geometry (you might need to slide the panel up or down to see this) Click on Attach List. Click on myobject and click on the Attach Button.
