So the situation is I have bought a huge texture bundle from Go Media, and all the files are named something like:
gma_tex_set05_clouds_01.JPG
gma_tex_set05_clouds_02.JPG (continuing through "filename"_03 -_30)
I want to rename them with the following structure:
clouds_01_gma.JPG
clouds_02_gma.JPG ( etc including "filename"_03.- _30)
So, I can do this but using 2 operations and I want to get it done in one operation.
I'm relatively new to Regular Expressions and String Substitution, but with a little research and a cheat sheet, I got MOST of what I need, but am still stuck on one point. I can't seem to get the "_gma" added at the END of the file but BEFORE the .jpg extension if using regular expressions to remove the first part (gma_tex_set05_). I found multiple ways to remove "gma_tex_set05_", including:
(in ALL instances below, the "Use Regular Expression" and "Replace All" checkboxes are CHECKED)
New Filenames:
String Substitution > Original Filename
Find: gma_tex_set05_
Replace: with (leave blank)
New Filenames:
String Substitution > Original Filename
Find: ^gma_tex_set05_
Replace: with (leave blank)
New Filenames:
String Substitution > Original Filename
Find: ((gma_tex_set05_))
Replace: with (leave blank)
New Filenames:
String Substitution > Original Filename
Find: ^.{14}
Replace: with (leave blank)
...etc. You get it... there are multiple ways to REMOVE the first part.
Now, in a separate operation, one NOT using RegEx, I can add the suffix "_gma" very easily.
New Filenames:
Current Filename > Name > Original Case
Text: _gma
EASY. BUT, I can't seem to COMBINE these functions in one operation to strip the "gma_tex_set05_" while simultaneously ADDING "_gma" BEFORE the .JPG suffix. I make the BEFORE distinction because I CAN add "_gma", but ONLY AFTER the .jpg extension:
New Filenames:
String Substitution > Original Filename
Find: ((gma_tex_set05_))
Replace: with (leave blank)
Text > _gma
Result = clouds_01.JPG_gma
However, when I FINALLY found some combination where the "Preview: Current Filename / New Filename" area shows what I'm trying to achieve, which is "clouds_01_gma.JPG", when I try to run it, it says "The regular expression is invalid."
New Filename:
String Substitution > Original Filename
Find: gma_tex_set05_
Replace: (leave blank)
String Substitution > Intermediate Filename
Find: (\....)
Replace: _gma
Run = The regular expression is invalid.
I've tried for 2 days and just can't seem to make it work. Again, I'm new to RegEx, so I don't know if it's me just not understanding a certain principal, or if trying to combine these 2 operations into 1 operation is just not possible. Any Ideas?
