PNG or TGA32 for semitransparent material

Questions & Answers
1

Is it better to use PNG or TGA32 for semitransparent materials in Unity?

2

Since Unity converts textures into an internal format the choice is rather in what tools you use to produce the respective textures. I would opt for PNG as I feel that the support for it is wider, though it really is only a choice in personal preference as both formats can convey 32 bit RBGA color information.
