Path Name ?
This wildcard is substituted with the file name, including its extension, in a given file path.
The wildcard is used in the following way:
{path.name.?}
For the following input (?) --> C:\Users\Administrator\Pictures\helmut-IO.ico
The output is going to be --> helmut-IO.ico
Ensure that the render node or server has access to file. If the wildcard is on a server-side stream, the streams container needs to have access to the file path.
