How to Use Magenta For Transparency in +2 Textures

This was originally a MeowMix forum guide, but I figured this should hopefully stem some questions so I decided to post it here.

How to Properly Use Magenta For Transparency in +2 Files

I've noticed that several people have asked for help about how to stop a magenta outline appearing on textures indexed with magenta, so I've decided to step in and squash those questions!  (This applies for CSPs too)

Needed

• Adobe Photoshop (I use 7.0 but it should work on any version as long as you can index.)
  
• A +2 texture to edit.
  
• Basic Knowledge of Photoshop (Able to recognize brush tool, etc.)
  

Instructions
(Click on a thumbnail to see the full picture.)

Step 1: Open your chosen +2 texture in Photoshop.  For my example we'll use Ike's hair.

Step 2: Edit whatever you wish about the texture.  In my example, I applied the chrome filter.

Step 3: Click on the color picker for the foreground and change it to 255,0,255.  Press ok.

Step 4: Select the brush tool and draw a little bit of magenta in an area where it's not touching any of your texture.



Step 5: If you haven't already, select the texture by control clicking the layer with your texture on it.  Go to Image>Mode>Indexed Color.  Set the pallet to local(perceptual), uncheck transparency and type the amount of colors the texture has in the color box (in Ike's case, 256).



Step 6: Almost done.  Press ctrl+shift+I (Windows) to invert your selection.  Go to Edit>Fill and choose foreground color (make sure the magenta is still set as your foreground color).



Step 7: Done!  Now save it and compile it using ASH, and poof!  No magenta outline!

If you have a question, post away!

You can manually hex it, so the hair has smoothed out edges.

...when you opened ikes hair, it already had the checkerboard background, how did you do that? when i open it, where yours is checkerboarded, mine is the color of ikes hair...
