png to tga - output in grayscale

[marco75]

I want to batch-process a folder of .png images and convert them to .tga (uncompressed Targa) and save them to another folder.

Specifically, I'm trying to port Doom 2 levels to Doom 3 format and using the hires textures for Doomsday as the source.

However, when I open the .tga images in Paint .NET, they come out in greyscale.
Picasa will display them as completely black
Adobe Photoshop won't load them at all

I want to get accurate color reproduction of the original bitmaps, but in Truevision Targe format!

What could I be doing wrong?

Thanks for reading.
