Is there a way to change the LUt extension form .CUBE to .cube. on export with this script in photoshop For MAC:
Chris Cox wrote:
The file extensions are written by the export plugin. (which incidentally has a comment that two studios wanted all caps extensions, but I failed to write down which ones in the comments)
To change the filenames, you'd want to add something at the end of doExportLUTs() that uses the supplied path and substitutes the desired extensions, then renames the file.
Thank you

// IN_PROGRESS - why can't ColorSync Utility open any profile with a grid of 160 or larger?
// 150 works, 160 fails -- sent samples in email to Apple on Nov 8, 2013; they are investigating
// DEFERRED - right to left filenames (Arabic) come out wrong because of appending "RGB" and file extensions
// This seems to be a bug in JavaScript's handing of strings, not sure we can solve it easily.
// It might possibly be handled by checking bidi markers in UTF8 stream and adding custom handling for appending text/extensions.
