Avatars are the digital representations of each user in a Cobalt Space. Cobalt allows you to use any one of three different Avatar types: BVH Motion 3D Avatars, non-motion 3D Avatars, and 2D "Poster" Avatars.

Switching Avatars

  1. Choose Cobalt > My Avatar...
  2. In the Choose Avatar window select one of the four tabs, depending on the type of Avatar you wish to select.
  3. In the right pane select Avatar file name. Click OK.
  4. The Enter scale factor dialog box automatically opens. Use it to size your object (you can also resize the object later using Cobalt's edit tools). By default the scale is set to 1, meaning the object will be imported at its originally created dimensions. You can the scale factor above 1 to increase the object's size or below 1 to decrease it.
  5. Click OK.

Creating a 2D Poster Avatar

You can make your own 2D Avatars based on photos or other images. The idea is to "knock" out the background of the image so that only the silhouette remains.

You'll need an image-editing program such as Photoshop or Gimp (free) that supports transparency.


  1. Create a new file in your image editor (make sure you've chosen to use a transparent background layer)
  2. Drag your image into the newly created file, adding it as a new layer on top of the background layer.
  3. Remove the background to define the silhouette. The simplest way to do this in an application like Photoshop is with the eraser tool. The magic wand tool works well if the background is comprised of a solid color. But if you have more advanced image-editing skills you may find a more efficient method.
  4. Resize the image to be no more than 425 pixels in height.
  5. Export the image as a .png file.
  6. Copy the image into Cobalt's avatar images directory (content>avatars>images).

Here's an example:

Tip: Add a temporary layer, filled with a solid high contrast color, in between your transparent background layer and your image layer. This will help you better see the border of the silhouette as you remove the background. Before exporting the .png remember to remove the temporary layer.

Bear in mind...since the poster avatar is based on a 2D image there is no back side. Both you and others in the Cobalt space will always see the "front" of the image.
