Many Wrap nodes have file name parameters to load or save data to files. These parameters can contain special syntax that will be interpreted by Wrap in a special way to produce the final file name.
Any sequence of
# symbols in the file name will be replaced with the current frame number. For example, the string
Sequence/Frame##.obj will be replaced with
Sequence/Frame01.obj in frame 1 or with
Sequence/Frame100.obj in frame 100.
Path variables start with the
$ sign and store different predefined paths. For example, in the string
$PROJECT_DIR/Texture.jpg the variable
$PROJECT_DIR will be replaced with the current project directory.
Wrap support the following path variables:
$GALLERY_DIR stores the current path to the Wrap gallery folder. You can change the
$GALLERY_DIR by editing the corresponding line in
$PROJECT_DIR stores the path to the current project file. For a new project that has not been saved yet, the
$PROJECT_DIR is empty.
$PROJECT_NAME simillary to the
$PROJECT_DIR, but stores the project name. File extension
.wrap isn’t included in the string.
$COMMON_DIR can store any user-defined path. Often it can be a network path to common resources, or a path to a folder that stores all the projects related to the current production.
Please use File > Set Common Dir to select a path for this variable.
In Wrap, loaded paths are automatically converted to contain the given path variables.
$PROJECT_NAME is never matched.
$COMMON_DIR’s priority is medium.
$PROJECT_DIR have the highest priority. Matching is greedy, so variables will be chosen to cover as many symbols as possible. A variable cannot replace a part of a name. For example,
C:\User\Dir10 will not be threatened as
$COMMON_DIR with value
