Working with documents
Before you can create a Bryce environment you need a document. A document can be either a blank scene or an existing file that you're going to edit.
Creating an Empty Scene
When you create a blank scene, Bryce opens the Document Setup dialog which lets you specify the aspect ratio and dimensions of the new scene.
To create a new document:
1 Choose File menu> New. The Document Setup dialog appears.
2 Enter values in the Document Resolution fields.
This is the absolute size of your working space expressed in pixels. You can enter any values you like here, though it's recommended that you do not exceed your available screen space if you can avoid it. You can work small and render large if you need to. The values in the Aspect Ratio fields will update automatically as needed.
3 Enter values in the Document Aspect Ratio fields.
These fields represent the Document Resolution as a ratio. Depending on the type of work you are doing, it may be more convenient to enter values here rather than in the resolution fields above. For instance, many video formats, as well as the standard 13" screen, are 3:4 aspect ratios.
The values in the Document Resolution fields will update automatically if you change the aspect ratio.
4 Enable the Constrain Proportions button if you want to preserve the current aspect ratio as you adjust the resolution.
5 Select a Render Resolution from the list.
This resolution sets the absolute size of your rendered image, expressed in pixels as a multiple of your document size.
You can work in one size as you build your scene and render that scene in a different size. For example, you could be working at Bryce's default size but need to render four times larger for print or four times smaller for a Web page. Rather than resetting your document resolution every time you render (thereby impacting your wireframe workspace), you can simply set a separate size for rendering. Think of Document Resolution as input, and Render Resolution as output.
The default resolution is 540 x 405, and the default aspect ratio is 4:3.
To set up a new document using presets:
1 Choose File menu> New Document. The Document Setup dialog appears.
2 Click one of the preset aspect ratios displayed along the right side of the dialog.
These presets are aspect ratios for many useful document types. The pixel values that are placed in the Document Resolution fields are either absolute (as in Legal or Letter paper sizes) or based on your available screen resolution (as in Maximum Recommended or Square).
Opening an Existing File
Bryce can open any file created in any previous version of Bryce (Mac® or PC).
To open an existing file:
2 Use the dialog controls to locate and open your file.
Merging scenes
You can merge two Bryce scenes using the Merge command. When you use this command, the scene you are opening is merged with the currently open scene. Objects from the scene you're opening are placed in your current scene at the same absolute coordinates that they previously occupied. Some information from the scene you're opening will be discarded, such as family names.
To merge two scenes:
1 Choose File menu> Merge. A dialog appears prompting you to save the current scene.
2 Click Save. The Open dialog appears.
3 Use the dialog controls to locate the file you want to merge and click Open.
The file you selected is merged with the current scene.
Holding down the Option/Alt key while performing this function will merge only the sky from the incoming scene.
