i am not quite sure if i understand what you are asking for but: via hrn inspektor you can set the String Type of an iobox to Filename which causes results in a visualisation of the string more suitable to filenames.
I d like to be able to decide the subfolder depth visualized in the string IObox. It may be done on a per number of letter basis or more logically on a per depth level.
shoule result in “vvvv files\permGradTexture.dds” if level set to 1
"GradTexture.dds" if level set to 0
etc.
I understand I can do that with a few nodes but since it is something I want to build better and more clean end user patch I d like it to be something you can select on the Inspektor
