Editing Scenes

Global Settings

Previz offers you a convenient way to tweak your basic model settings including lighting and positioning to make sure your model is rendered exactly the way you want it. These options can all be controlled in the Viewer tab in the scene editor. Changes are rendered in real time and saved automatically.

Change Background Color

You can change the background that appears behind your model.

To edit the background color:

1. In the content view pick the scene you wish to edit.
2. Whilst in edit mode in the sidebar navigate to the Viewer tab and then the World sub-tab.
3. In the Background Color input click the color swatch or text input field. You can choose any color from the picker or enter a hexadecimal color code.

Illumination

The illumination field allows you to edit the lighting exposure for the scene.

Note: This is independent of any lights you may have within your scene.

To edit the lighting exposure:

1. In the content view pick the scene you wish to edit.
2. Whilst in edit mode in the sidebar navigate to the Viewer tab and then the World sub-tab.
3. In the Illumination field adjust the lighting exposure by either clicking and adjusting the slider or by editing the number input field.

Note: The slider adjusts a range from 0 to 2. The number input will allow any value.

Global Lighting

There are two lights added to every scene by default.

1. Global Ambient Light
2. Global Hemisphere Light

It is up to you whether to use these or not. If you have setup lighting in your imported 3D scene it is likely that you will want to turn both of these off.

Global Ambient Light

This light globally illuminates all objects in the scene equally. This light cannot be used to cast shadows as it does not have a direction.

1. In the content view pick the scene you wish to edit.
2. Whilst in edit mode in the sidebar navigate to the Viewer tab and then the World sub-tab.
3. In the Illumination field adjust the lighting exposure by either clicking and adjusting the slider or by editing the number input field.
