Understand environments, ambient occlusion, and rendering in VRED.
Transcript
00:03
Welcome to VRED.
00:05
The default environment in VRED is a Studio.
00:08
It contains a Dome that the environment is applied to and a shadow plane.
00:14
You can apply your own images to the environment.
00:18
However, for now, we will use one of the example environments in the Asset Manager,
00:24
Select the Environment tab, then the Autodesk VRED Assets folder to display a list of environments.
00:31
Scroll down and left mouse button drag Pacific Rd. onto the environment Dome to apply it.
00:39
You can add multiple environments and switch between them by clicking on these boxes to toggle their visibility.
00:47
Next, we'll calculate ambient occlusion.
00:51
Ambient occlusion is proximity-based shadows.
00:55
Calculating it creates shadows in the gaps of your model and greatly improves the realism of your rendering.
01:02
So select the visualization menu and click on Ambient Occlusion Rendering.
01:09
You can see that there are no shadows on the model.
01:11
So let's calculate ambient occlusion and see the difference.
01:15
Go back to the Scenegraph and select the top node of the car.
01:20
Select Scene, Bake Light and Shadows, and in the Direct illumination section, click Ambient Occlusion.
01:30
Use the default settings and click Calculate All.
01:34
Depending on your computer's capabilities, this is likely to take several minutes.
01:39
Now you can see what's added with the Ambient occlusion.
01:43
In the visualization menu, select Realistic Rendering.
01:48
You may not have noticed, but the car is slightly below the ground of the environment.
01:54
With the top node of the car still selected, click on Transform in the toolbar.
02:00
This translate manipulator should be displayed.
02:04
If a different manipulator is shown, click and hold the arrow and select Transform Manipulator.
02:12
Hold the shift key and left mouse button drag the arrow until the bottom of the tires is just above the environment.
02:21
Deselect Transform and Shift + right mouse button Click to deselect the model.
02:27
Now let's prepare for the final task of rendering.
02:31
Deselect Headlights from the toolbar if it was selected.
02:35
This is a default light that won't be needed now.
02:40
Position the model for rendering.
02:41
Select Antialias from the toolbar.
02:45
Ray Tracing calculates reflections, refractions, and light-based shadows.
02:52
Antialias smooths edges and improves the model's appearance.
02:56
Select Render from the icon bar.
02:60
In the file output Render Settings tab, change image size presets to HD1080.
03:09
In the General Settings tab, set Adaptive Sampling to Ultra High Quality for production-level rendering.
03:18
Click Render to name the image and specify the location.
03:22
Then click Save.
03:24
The render may take several minutes.
03:27
Navigate to the image and view your render.
03:30
And finally, go to File < Save As and Save your work.
03:35
The native format for VRED is .vpb.
