There are tons of content add-ons that you can purchase and use in Bryce. Unlike content used in DAZ Studio, where the content will show up automatically in the Content Tab when properly installed, content add-ons in Bryce must be imported.
This requires you to know how to import, the type of file you are importing, and the location of the file. Most Bryce add-ons are Materials (.mat), Objects (.obp), or Skies (.bsk).
There are several separate libraries in Bryce:
The files are in .mat format. To enter the Material Library, choose the EDIT Palette above. Then click the 'triangle' to the right of it. It's actually not necessary to choose the EDIT Palette first, but it may make navigation easier for the first time. The keyboard command to enter the Material Lab is CTRL + M (CMD + M). Keep in mind that the Material Library and the Material Lab are not the exact same place.
The files are in .obp format. “Obp” stands for “Bryce Object Preset.” To enter the Object Preset Library in Bryce, choose the CREATE Palette at the top. Then press the triangle to the right of the word 'Create.'
The sky presets are in .bsk format (Bryce Sky). To enter the Bryce Sky Library, click the triangle to the right of the “Sky & Fog” palette.
There are other file formats in Bryce, such as .bto (Bryce Tree), but these are not typically part of importing a Bryce add-on product.
Once you know the file type and the location, you can enter the relevant library and import the file.
Enter the library that corresponds to the kind of preset you are going to import. So, if you want to import a Material Preset (.mat), you should enter the Material Library.
Within each library, there are several categories and groups in each folder. Before you import into that library, you'll want to choose which subfolder to use. You can even create a new group within a category. It's best to choose an arrangement that makes sense to you.
In Bryce 6 and 7, for example, in the Materials Library, you'll find these categories:
Contributing Artists (Bryce 7 only, not in 6)
Pro Materials (Bryce 7 Pro only)
So, if you are choosing to import an add-on with new metal textures, you may want to choose to import it into the 'Metals' category. Select 'Metals,' so you're in that category.
Within the category, you can choose an existing group or create a new group. For example, in Metals, you'll find several groups (Automotive, Bright, Christmas Balls, etc.). Select the group you want by clicking on its name. Alternatively, you can make a new group by clicking on the “+” Plus sign below. A window will open in which you can type the name of the new category. Then press the 'check mark' to the right to complete the creation
Now all that's left is to import the file. You'll need to know where the file rests in folder structure on the hard drive. For most products, the readme will tell you the paths of the files. Otherwise, you'll need to browse the hard drive.
To import, press the button labeled 'Import.' A window will open to allow you to browse to and select the file. By default, only files of the format of the library you're in will be visible (.mat, .obp, .bsk). Browse to the file to import. Once you've found the file, double-click it. One or more presets will now appear in the library. Each preset will appear as a square thumbnail.
