Description

By using the mask parameter with a command that supports it, you can hide unwanted parts of something. For example, you may have a picture of a tree stored in an image file named tree5.jpg but want to display only the tree and not the background part of the image. To do this, you need to specify that a mask file will be used, and the mask file needs to be a zipped bitmap image with the areas you want showing light or white and the areas you want hidden dark or black. If the mask file has the same name as the texture file except for the different extension and a letter "m" added just before the .zip file extension on the mask file, then the animate command's mask parameter will find it without you having to specify a mask filename, but in other cases the mask file's name will need to be specified.

The nomask option may be use with the animate command to explicitly mark an animation as not masked. This option is specifically for compatibility with older versions of the Active Worlds browser. By default, in Active Worlds 3.0 or later, animations and textures are not masked. The nomask option is therefore not needed unless the build is intended to be viewed in a pre-3.0 version of the Active Worlds browser.
