Making transparent tga files

How do I make a transparent tga file in Photoshop? The tga file included in the source code of the tutorial from Lighthouse 3d is working fine but the files I am making are being loaded with the transparent part being white.

I am using the code from here

  1. create image
  2. in the “channels” palette, click the “new channel” button
  3. paint into the alpha channel
  4. Save As… TGA - 32-bit - no compression.

Thanks!! Works great… :slight_smile:
