3.4_Editing Materials

0:00 This lesson covers the basics of editing materials after they’ve been applied to your model.

0:07 As noted in the previous lesson, the scale on most of these materials looked to be a bit too small, which shows the tiling more prominently...something we want to avoid.

0:19 The easiest way to scale a texture is to select a material in the Materials browser…let's use the planting area groundcover texture…

0:29 …and then right-click it and select ‘edit’ – which brings up some editing options.

0:35 One of the options is to manually enter a new width and height. Try entering ’15’ feet and see now that the texture looks a lot better.

0:48 Let's do the same thing for the other materials.

0:53 For the concrete walks, enter ’10 feet’…

1:04 …the concrete walls, let's do ’10 feet’ again…

1:14 …and finally ’10’ feet for the plaza pavers.

1:22 The next way we’re going to modify some of our textures is to rotate them manually to get them in the right position.

1:30 If you right-click on a texture, ike the plaza pavers, you can then select ‘Position’ from the ‘Texture’ context menu.

1:39 After we do that we can see the full size of the texture and its repeating tiles sort of ghosted in beyond our surface boundary.

1:48 Also note the four colored pins in each corner.

1:53 We won’t cover all of the features of manually editing materials here…just the most common like panning, rotating, and manually scaling.

2:03 If we click down on the center, we can pan or move the texture around…which is useful when needing to align a paver or score joint.

2:13 Next, let’s rotate the texture to realign the pavers to point towards the center point of the walk’s arc.

2:21 Click the green pin and hold and drag to rotate.

2:26 Holding option key on Mac or Alt key on PC, keeps it from snapping to the protractor points – which may make it easier to align with adjacent geometry.

2:37 Be careful not to scale the texture while rotating as we already scaled it in the materials browser.

2:44 Of course you could scale manually using this method instead but it may be less precise than our previous method.

2:51 Let’s rotate the other two paver areas.

3:08 And that’s it for this plaza group.

3:11 Let’s do the same thing for our walls which, if pasted in as vertical instead of horizontal, would need to be rotated as well.

3:21 If we’re trying to rotate a texture on a curved surface, like a lot of our walls are, then we won’t be able to.

3:28 We first need to turn on our hidden geometry in order to isolate just one part of the curve…then edit that through the ‘Position’ context menu again.

3:54 We can now sample just that rotated part of the wall and then turn off the hidden geometry…select all the walls…and then paste the material.

4:08 If there are any remaining areas that are giving us trouble, then we can just go in and position manually.

4:34 Next we’ll briefly review how to change colors and textures directly in SketchUp.

4:41 Let’s say the paver texture is a bit too reddish and we want it more beige-looking…

4:47 …or that it’s too saturated and we want it a bit more subtle so it doesn’t pop so much.

4:52 Either of these changes are easy to do.

4:55 For this step, we’ve actually split the screen to see how it looks on Mac vs PC...

5:00 ...which is a bit different as Mac uses the OSX color manager while on PC, colors are shown in panel window like all the other settings.

5:11 So with the Materials, or color window showing, find and double-click on the texture you want to edit.

5:17 Let's use the pavers again.

5:20 Then switch over to the color wheel tab.

5:23 Here we can adjust opacity so that you can see through it...not that we want to do that for our texture.

5:31 Or you can change hue...saturation....orlightness.

5:44 The last way we can edit a material is externally or outside of SketchUp in a photo editing program such as Photoshop.

5:52 Note that I’ve already set Photoshop to be my default editor in the ‘Preferences/Applications’ section and you can do the same thing if you’d like.

6:02 To see this in action, let’s double-click the pavers texture again.

6:07 This time, we’ll select ‘edit’ from the drop down and we'll watch as it sends the image automatically to Photoshop.

6:15 Once in Photoshop, we can make whatever changes we want.

6:20 Let’s say we want one of the pavers to be a slightly different color for some reason…we can make that change...

6:31 ...and then save this file in Photoshop…

6:36 ...then switch back to SketchUp and we can see our edited texture automatically update in the model.

6:46 I’m going to undo that color change step and save the material again in order to get our original texture back as that was just to illustrate the concept and I don’t really want that paver different from the others.

7:01 That’s it for adjusting and editing our model’s materials.
