Output filename

Axelsp

Sorry everyone, this is prolly a easy question, but Im unable to find it on the docs. Any help is mostly appreciated.
I need to change my output file name to something other than: "Model [AlbedoM].psd"
Those square brackets are very difficult to deal with. Any ideas on how to change that to: "Model_AlbedoM.psd" ?
Many many thanks !

Yes, more context is needed.
