Photoshop Normal Map Action Set
polycounter lvl 18
Just added the rotate functions this morning and decided it might be worth sharing.

Cut and paste from my site:
"Set of useful actions for working with normal maps in Photoshop.
Overlay: Levels blue channel of current layer to 127 and sets the blend mode to overlay. Used for overlaying additional normal map detail.
Normalize: Just does a nVidia normal map filter normalize on the current layer.
Normalize (flatten): Flattens the image and does a nVidia normal map filter normalize.
Rotate 90 CW: Rotates current normal map layer 90 degrees clockwise and fixes your red and green channels so that it doesn't break your normal map.
Rotate 90 CW (inverted Y): Rotates current normal map layer 90 degrees clockwise and fixes your red and green channels so that it doesn't break your normal map. For normal maps that use the inverted Y convention.
Rotate 90 CCW: Rotates current normal map layer 90 degrees counter-clockwise and fixes your red and green channels so that it doesn't break your normal map.
Rotate 90 CCW (inverted Y): Rotates current normal map layer 90 degrees counter-clockwise and fixes your red and green channels so that it doesn't break your normal map. For normal maps that use the inverted Y convention.
Rotate 180: Rotates current normal map layer 180 degrees and fixes your red and green channels so that it doesn't break your normal map.
Following the conventions set by Doom3 and the nVidia Normal Map filter:
regular Y - green channel: black = up, white = down
inverted Y - green channel: white = up, black = down
*normalize functions require nVidia Normal Map Filter .
"
Hopefully you guys find it useful.
EDIT 1: The normalize actions were recorded using the latest version of the nVidia normal map filter linked above. They will not work if you're using an older version.
EDIT 2: Updated the download with inverted Y actions, see my post below for details.

So I added inverted Y versions of the rotate 90 actions.
Following the conventions of the nVidia normal map filter and Doom3:
regular Y - green channel: black = up, white = down
inverted Y - green channel: white = up, black = down
Sorry for any confusion/problems this may have caused. Please redownload if you downloaded before.

I wonder if you have these actions on your new site somewhere? I was editing the Normal_Map#Painting section of the wiki and remembered this thread. Your old site is of course gone, but it would be great if I could link to your new site to get the tools.
If you don't want to go thru the trouble of editing your site to add the zip, I could instead upload the zip to the wiki and add a credit to you that points to your site. Looks like I have the latest version here.
Yeah, I need to get around to updating my site...
