To avoid problems which can occur with very long command lines, the names of the projects are allowed to have up to 20 characters (the extension does not count for this limit).
Only letters, numbers, hyphen and underscore are allowed in a filename:
[a-z] [A-Z] [0-9] - _
You can use the “_” sign (underscore) to replace spaces
To prevent parsing problems during the rendering on our farm, we also recommend you do follow the same rules for your assets (scene, textures, objects, output bitmaps etc.).
It is not possible to have two projects with the same name in the waiting or rendering list: you can version your filenames with numbers to avoid confusion.
