Switching RGB channels post Zbrush

Whats wagging guys? I recently made a normal map of two arms in a single sub tool using z mapper. But the weirdest thing happened. My Blues are all fine, but on my right arm the greens and reds are switched.

I was wondering if there was a way to swap the values of Red and Green in the .tiff file I exported out. Preferably a way to do it in photoshop CS4.

I know its not really a Zbrush question, but I figure this would be the best place to ask a normal map question.

Thanks for the look.

That should be easy enough. I have CS2 but I doubt if CS4 is any different:

  1. In the Channels palette, right-click on the Red channel and choose Duplicate Channel. Make sure the same document is selected as Destination. This will temporarily store a copy of the red channel.
  2. Select the Green channel only, Ctrl+A to select it all and Ctrl+C to copy.
  3. Select the Red channel only. Ctrl+V to paste the Green channel on it.
  4. Select the Red Copy channel, Ctrl+A to select it all and Ctrl+C to copy.
  5. Select the Green channel only. Ctrl+V to paste the Red Copy channel on it.
  6. Select the Red Copy channel, right-click and choose Delete Channel.
  7. Select the RGB channel, you’re done.

HTH,

thanks marcus.
