Is TGA the best format to import?

Looking inside a scene file package content, all PNGs or JPGs images are converted to TGAs… Is better already import in this format?


Not necessarily…
TGA files are supporting alpha channels, are fairly widely used,
and as far as I know, were designed to run very well with MS-DOS colour applications.

Anyway, use PSD, PNG, TGA… whatever you prefer… (all supporting alpha channels)

My preferred choice is PSD (using Photoshop as my main Editor).
Excellent working-format for manipulation and adjustments, separate image channels,
layers, masks etc… After editing it can be saved to any desired format.
