0:05 Hey everyone. Welcome to this lesson on using V-Ray and SketchUp.

0:11 In this video, we're going to look at just the very basics of how to get started with V-Ray.

0:17 And that means we're just going to focus on a few of the settings to ease you in to this powerful rendring tool.

0:26 Let's get started.

0:29 When you have V-Ray installed, it creates four (4) new toolbars that you can open.

0:36 We are going to start with just one.

0:40 The 'V-Ray for SketchUp' toolbar.

0:43 And in this toolbar, we are only going to use this top button to open the V-Ray 'Asset Editor'.

0:51 You can also open this in the menu under 'Extensions/V-Ray/Asset Editor'.

0:59 The Asset Editor is the main hub we will use to control our rendering.

1:06 Do not worry about all these various settings...just focus on these few tabs at the top –

1:13 which are the major categories such as: 'Materials'...'Lights'...and 'Render Settings'.

1:22 And on each side of the Asset Editor are expandable windows.

1:28 Click on the arrow on the left and right to open and close these additional settings.

1:37 That's really all there is to finding your way around the Asset Editor.

1:42 The top categories and the expandable side windows.

1:48 Now let's create some basic geometry and start a render.

1:53 Let me draw a few shapes...pull them up and make the groups or components.

2:01 We just need a basic starting point.

2:10 In the Asset Editor, this tapot icon will start a render...however, there are two types of renders we could start.

2:20 A high-quality final rendering...or a lower quality 'Interactive' rendering that will update in real time with changes we make to the model.

2:33

2:34 Click on the gear icon to open the render settings and toggle 'on' the interactive mode.

2:44 Notice the tapot icon change from a final render to an interactive render.

2:52 The interactive icon has a hand over the teapot.

2:55 Now click to start an interactive render.

2:59 Under the 'Interactivity' slider, choose a low or medium setting to speed up our rendering time.

3:07 Now click back into the SketchUp scene and zoom and orbit around to see how the interactive render reflects the same view.

3:19 Let's edit some groups or components to show that the rendering will continue to update with these changes.

3:30 Notice that the ground shadows are on in SketchUp but they're not showing up in our render.

3:38 This is because in SkectchUp will cast shadows on an imaginary ground plane...

3:43 but to show up in our V-Ray render, we need to create some geometry.

3:49 Drawing a simple circle or rectangle will do fine for now – it creates a surface that V-Ray can use to cast shadows on.

3:59 Let me group this circle and try changing the shadows in SketchUp – which will update in our render window as well.

4:08 If you ever want to pause or stop the rendering, you can click again on the teapot icon.

4:16 Right now it has this red dot indicating the render is active. Click once to pause the interactive rendering...or restart it.

4:31 You can do the same with the rendering window as well, clicking on the stop sign or the teapot icon.

4:38 This rendering window is also called the 'Frame Buffer' so you may hear it referred to as the rendering window or the Frame Buffer.

4:52 So our rendering is pretty basic.

4:56 Let's apply some materials to a few of these objects and show how the materials will be synced between SketchUp and V-Ray.

5:04 If we look at the materials browser in SketchUp, there are probably some colors here from the default SketchUp person.

5:12 In this version of SketchUp, Laura is the default person and the colors are named based on Laura's component.

5:19 Looking in the Asset editor, click on the 'Materials' tab and you'll see the exact same material names.

5:27 Let's rename a material here. Double-click to rename a material. Hit enter (return) to finish.

5:35 And now, looking back at the SketchUp materials browser, that change is made here too.

5:45 The point is that you can apply materials or make changes in either place.

5:53 I'll use a few of these colors to paint some objects in our scene.

5:59 And those colors now show up in the interactive render.

6:04 If I choose a completely new color, that will also show up in the Asset Editor.

6:13 So far, these are all basic SketchUp colors...but let's have a look at some of the default materials that come with V-Ray.

6:21 Expand the left side window, and then expand the materials list.

6:27 There are a lot of options here which are fun to try out.

6:32 I'll just stick to some car paint for now.

6:35 An easy way to apply V-Ray materials is to select surfaces or objects in SketchUP...

6:43 then in V-Ray, right-click on a material and choose 'Apply to Selection'.

6:51 Let me choose some different objects...right-click...and choose 'Apply to Selection'.

7:01 These new materials now show up in our scene and in the rendering window. You can see the reflections that are part of this car paint material.

7:11 Now this is an introduction video, so we're not going to explore materials in depth...

7:19 but if you want to start exploring individual material settings, that can be found by expanding the right side of the Asset Editor.

7:29 A simple place to start is just to change the 'Diffuse' color of a material – which you can think of as the base color.

7:40 Ok, let's review what we've learned so far.

7:44 We know that the hub for working with V-Ray settings is the Asset Editor.

7:49 And that we can sort through the main categories with the top icons.

7:55 We learned to expand the right and left-side panels for additional settings.

8:01 We started an interactive render as a way to test various settings and see the real time updates change as we make changes in the model.

8:10 We also applied a few basic materials using both SketchUp and V-Ray.

8:17 Try this out on your own using some basic shapes and groups.

8:22 And in the next video, we'll make some simple lighting changes, go a little bit deeper into materials, and set up for a final render that we can save to our computer.
